[v3,00/15] Support OVTI7251 on Microsoft Surface line

Hello all

This series extends the OV7251 driver so it's functional on the
Microsoft Surface line of laptops, where it's used as the IR
camera for face login. The camera sensor is connected to a CIO2
device which packs the 10-bit greyscale data into 25 pixels per 32
bytes similar to the IPU3 formats for Bayer data, so I also added
a new format to describe that and added it to the ipu3-cio2 driver's
list of supported formats. 

Series-level changes:

	- Added patches 12-15, which extend the driver's controls to fulfil libcamera
  requirements.

Thanks
Dan
