Changes in v2:
- Added selects and depends statements to Kconfig entry
- Fixed copyright year
- Stopped including in .c files headers already included in .h
- Fixed uninitialized variable in iterator
- Only check vvalid member in interrupt function and wait
unconditionally elsewhere
- __maybe_unused for the PM ops
- Initialise the subdevice after setting up PM
- Fixed the remove function for the driver to actually do
something.
- Some minor formatting changes
- Fixed the quantization member for the format
- Changes accounting for the v2 of the media jobs framework
- Change min_queued_buffers to 0

There is no need to select RESET_CONTROLLER, the API has stubs to allow
compiling without it.
Ah - thanks for pointing that out
