Update the configuration supplied to APB-A to use new parameters, while
keeping compatibility with legacy camera modules.
Substitute hard-coded clock frequency with information provided by camera
module, and retrieve the maximum CSI Long Packet length from the
returned stream configuration.
This patch requires APB-A csi-tx driver to be updated to comply with
newly defined bandwidth requirements.
Testing Done: preview, capture and video recording with updated csi-tx
driver on APB-A side, and legacy white camera module firmware

As camera specification gets updated, and Configure Stream Response
payload modified, define here the new response structure.
In order to not break non up-to-date camera modules, keep the existing
structure and add the _deprecated suffix to it.
Add the size of both new and old structure in order to discriminate
dynamically which version of Camera Specification the camera module
implements and translate deprecated version of configure_streams response
in the new one.
In order not to break camera functionalities, for testing purposes,
hard-code values the APB-A CSI Tx driver still requires for proper
interface configuration (lines_per_second and num_lanes)

Camera modules will stop reporting the number of lines per second,
hardcode the parameter in the driver until the APB-A CSI-2 TX
configuration protocol gets updated as well to use a more appropriate
form of bandwidth information.
The number of data lanes is also hardcoded as it should not depend on
the module's CSI-2 bus configuration.

phy-sun4i-usb now has proper dr_mode handling, it always registers an
extcon, and sends a notify with the mode (even when in peripheral- /
host-only mode) at least once.
So we can simply the sunxi musb glue by always registering its extcon
notifier and relying on sunxi_musb_work() to enable vbus when in
host-only mode.
This also enables host- and peripheral-only mode with vbus monitoring.

This file doesn't do anything modular and hence while the tristate
Kconfig used for the gpio portion is fine, it recently got swept up in
an audit of files using the module.h header but not using any modular
registration functions.
However it is not compiled in any of the normal build coverage, and
so some remaining extraneous MODULE macro use were not found until a
randconfig from the kbuild robot came across it.
Here we remove the remaining no-op MODULE macros from the built in
portion of code relating to this Kconfig option.

If there were less than 2 entries in the multipath list, then
xprt_iter_next_entry_multiple() would never advance beyond the
first entry, which is correct for round robin behaviour, but not
for the list iteration.
The end result would be infinite looping in rpc_clnt_iterate_for_each_xprt()
as we would never see the xprt == NULL condition fulfilled.
