Sensor drivers which implement set_selection V4L2_SEL_TGT_CROP expect
v4l2_subdev_state.pads[pad].try_crop to have valid contents when calling
set_fmt with which == V4L2_SUBDEV_FORMAT_TRY since the crop-rectangle
may influence the available image size.
Just passing an uninitalized struct v4l2_subdev_pad_config from
the stack to set_fmt with which == V4L2_SUBDEV_FORMAT_TRY will result
in wrong results with such drivers.
Store a per sensor v4l2_subdev_pad_config and add a new
atomisp_init_sensor_crop() function to initialize this before
registering /dev/* nodes with userspace.
Sensor drivers which implement the selection API will allow
the atomisp to properly deal with the extra padding the ISP wants
on a per sensor basis instead of hardcoding this.
atomisp_init_sensor_crop() stores the native and active rects
of the sensor in preparation for using these for this.

There are a number of bugs in atomisp_try_fmt_cap() and atomisp_set_fmt():
1. atomisp_try_fmt_cap() uses atomisp_adjust_fmt() which adds the sensor
padding to the width passed to atomisp_adjust_fmt() to calculate
bytesperline. This is buggy for 2 reasons:
a) The width passed to atomisp_adjust_fmt() already contains
the sensor padding.
b) The fmt returned by atomisp_try_fmt_cap() is the fmt outputted by
the ISP and the sensor padding applies to the input side of the ISP
not the output side. The output side of the ISP has its own padding /
pitch requirements which have nothing to do with the sensor.
Both these issues are fixed in this refactor by switching to
ia_css_frame_pad_width() to calculate the padding.
2. atomisp_set_fmt() takes the passed in bytesperline value without
doing any validation on it and then passes this unchecked value to
the configure_output() callback.
If bytesperline converted to pixels is > 1920 ia_css_binary_find()
will fail to find a valid binary for the preview pipeline triggering
a dump_stack_lvl() call inside ia_css_binary_find() and causing
atomisp_set_fmt() to fail.
This is fixed by making atomisp_set_fmt() call atomisp_try_fmt()
first which we override the userspace specified bytesperline with
the correct value.
Besides this bug there is also a bunch of weirdness and a lot of
duplication in the code:
1. atomisp_try_fmt_cap() adds the sensor padding itself but then
it gets substracted again in atomisp_adjust_fmt() not doing
the addition + substraction in the same place makes the code hard
to follow (weirdness).
2. atomisp_set_fmt() starts with basically an atomisp_try_fmt() call,
except that the only atomisp_try_fmt() caller: atomisp_try_fmt_cap()
adds the sensor padding itself rather than letting atomisp_try_fmt()
do this (duplication).
3. Both atomisp_try_fmt_cap() and atomisp_set_fmt() contain code to
lookup the bridge-format matching the requested pixelformat and
both will fallback to YUV420 if this is not set (duplication).
4. Both atomisp_try_fmt_cap() and atomisp_set_fmt() contain code to
fill in the passed in v4l2_pix_format struct (duplication).
Cleanup all of this (and fix the bugs mentioned above) by:
1. Adding a new atomisp_fill_pix_format() helper which properly uses
ia_css_frame_pad_width() to calculate bytesperline.
2. Move all sensor padding handling to atomisp_try_fmt() and
make atomisp_try_fmt() fill the passed in v4l2_pix_format struct.
3. This reduces atomisp_try_fmt_cap() to just a small wrapper around
atomisp_try_fmt().
4. Replace the DIY try_fmt code at the beginning of atomisp_set_fmt()
with atomisp_try_fmt(), this will also override/fix the bytersperline
passed by userspace.
5. Replace the DIY v4l2_pix_format filling at the end of atomisp_set_fmt()
with atomisp_fill_pix_format().

Note this is a quick fix for this since the entirety of
atomisp_gmin_platform.c will be removed once all atomisp sensor
drivers have been moved over to runtime-pm + v4l2-async device
registration.

Ideally, strlen(cur->string.pointer) and strlen(out) would be the same.
But this code is using strscpy() to avoid a potential buffer overflow.
So in the same way we should take the strlen() of the smaller string to
avoid a buffer overflow in the caller, gmin_get_var_int().

On these boards, vdd_bat is 16bit, not 24bit. Reading them as 24bit
values yield garbage values because of the additional byte, which is a
configurable fan trippoint[1].
So set their mode to mode_voltage_16bit = 3 instead of
mode_voltage_24bit = 1.

Drop v4l2_get_acpi_sensor_info() the 2 sensor drivers which were
using this have both been converted to v4l2-async probing, relying
on the atomisp_csi2_bridge.c code to add the GPIO mappings instead.

Switch the atomisp-gc0310 driver to v4l2 async device registration.
After this change this driver no longer depends on
atomisp_gmin_platform and all atomisp-isms are gone.

Turn the atomisp-ov2680 driver into a standard v4l2 sensor driver:
1. Stop filling camera_mipi_info
2. Stop calling v4l2_get_acpi_sensor_info() this will be done by
atomisp_csi2_bridge_parse_firmware() now
3. Switch to v4l2 async device registration
After this change this driver no longer depends on
atomisp_gmin_platform and all atomisp-isms are gone.
While at it, also add missing mutex_destroy() to ov2680_remove().

Add support for using v4l2-async sensor registration.
This has been tested with both the gc0310 and the ov2680 sensor drivers.
Drivers must add the ACPI HIDs they match on to the supported_sensors[]
array in the same commit as that they are converted to
v4l2_async_register_subdev_sensor().
Sensor drivers also must check they have a fwnode graph endpoint and return
-EPROBE_DEFER from probe() if there is no endpoint yet. This guarantees
that the GPIO mappings are in place before the driver tries to get GPIOs.
For now it also is still possible to use the old atomisp_gmin_platform
based sensor drivers. This is mainly intended for testing while moving
other sensor drivers over to runtime-pm + v4l2-async.

Fix a compiler warning:

The 'settings' variable is actually always initialized, but the
compiler isn't quite able to figure that out. Just initialize it
to 0 to avoid this warning.

This is a preparation patch for making atomisp work with
