Add support for new devices:
* Analog Devices AD9652 16-bit 310 MSPS ADC;
* Analog Devices AD9643 14-Bit, 170/210/250 MSPS ADC;
* Analog Devices AD9649 14-bit 20/40/65/80 MSPS ADC.
Note all these parts have subtle differences in their programming model
(different scales, number of channels, etc..) so fallbacks are not
possible.

If there's only one possible scale, there's no way to change the Vref
select in the device so avoid reading the register in ad9467_get_scale().
In this case, it makes no sense to provide the .read_available()
callback nor allowing for writing the scale attribute.
Note this is in preparation for supporting a new device that only has
one possible scale.

Add new variables to the per chip info structure:
* test_points: Number of valid test points for calibration;
* has_dco_invert: Supports inverting DCO (Data clock output) polarity;
* dco_en: Specicic mask to enable DCO delays.
This is in preparation for supporting new parts with subtle differences
in how to configure the hardware.
Note that with the new test_points variable, we also add a new
calib_map_size to 'struct ad9467_state' so we know our map size
depending on how many test points we have and if we can run the
calibration in the inverted state or not.

The calibration process mixes the support for calibrating multiple
channels with only having one channel. Some paths do have 'num_channels'
into account while others don't.
As of now, the driver only supports devices with one channel so the
above is not really a problem. That said, we'll add support for devices
with more than one channel, hence let's properly make the calibration
process to work with it.

'masklength' is supposed to be an IIO private member. However, drivers
(often in trigger handlers) need to access it to iterate over the
enabled channels for example (there are other reasons). Hence, a couple
of new accessors are being added:
* iio_for_each_active_channel() - Iterates over the active channels;
* iio_get_masklength() - Get length of the channels mask.
The goal of these new accessors is to annotate 'masklength' as private
as soon as all drivers accessing it are converted to use the new
helpers.

The TWA_NMI_CURRENT handling very much depends on IRQ_WORK, but that
isn't universally enabled everywhere.
Maybe the IRQ_WORK infrastructure should just be unconditional - x86
ends up indirectly enabling it through unconditionally enabling
PERF_EVENTS, for example. But it also gets enabled by having SMP
support, or even if you just have PRINTK enabled.
But in the meantime TWA_NMI_CURRENT causes tons of build failures on
various odd minimal configs. Which did show up in linux-next, but
despite that nobody bothered to fix it or even inform me until -rc1 was
out.

All batches of the Pine64 Pinebook Pro, except the latest batch (as of 2024)
whose hardware design was revised due to the component shortage, use a 1S
lithium battery whose nominal/design capacity is 10,000 mAh, according to the
battery datasheet. [1][2] Let's correct the design full-charge value in the
Pinebook Pro board dts, to improve the accuracy of the hardware description,
and to hopefully improve the accuracy of the fuel gauge a bit on all units
that don't belong to the latest batch.
The above-mentioned latest batch uses a different 1S lithium battery with
a slightly lower capacity, more precisely 9,600 mAh. To make the fuel gauge
work reliably on the latest batch, a sample battery would need to be sent to
CellWise, to obtain its proprietary battery profile, whose data goes into
"cellwise,battery-profile" in the Pinebook Pro board dts. Without that data,
the fuel gauge reportedly works unreliably, so changing the design capacity
won't have any negative effects on the already unreliable operation of the
fuel gauge in the Pinebook Pros that belong to the latest batch.
According to the battery datasheet, its voltage can go as low as 2.75 V while
discharging, but it's better to leave the current 3.0 V value in the dts file,
because of the associated Pinebook Pro's voltage regulation issues.
