[v2,00/16] Updates to ov9282 sensor driver

Message

This series adds to the functionality of the Omnivision OV9282 driver to make it
usable with libcamera.

Tested on a Raspberry Pi with OV9281 sensor (same as OV9282 but with alternate
CRA on the optics)

Changes in v2
Collected the relevant R-b tags from Jacopo (many thanks)
Patch 5 - replaced macro OV9282_NUM_MODES with direct use of ARRAY_SIZE (Sakari)
Patch 6 - reworded commit text (Jacopo)
Patch 7 - correct typo (250 instead of 151) (Jacopo)
Patch 8 - moved setting CSI2 clock mode from streamon to power on (Sakari)
Patch 10 - double empty line removed (Jacopo)

No response on patch 11 with regard policy on whether V4L2_CID_VFLIP & HFLIP
should be with regard sensor native orientation or initially submitted driver,
so I've left it as is.

No response on patch 16 as to whether all sensor drivers with controls should
have V4L2_SUBDEV_FL_HAS_EVENTS and subscribe_event/unsubscribe_event handlers,
so again it's unchanged. It fixes a v4l2-compliance failure and therefore would
appear to be valid.
