media: i2c: imx296: Add horizontal/vertical flip support

commit  df4311d26614414882adde1b91fcc327890b184d from
https://github.com/raspberrypi/linux.git

 rpi-6.1.y

Add support for setting horizontal and/or vertial flips in the IMX296
sensor through the V4L2_CID_HFLIP and V4L2_CID_VFLIP controls.

Add a new helper function to return the media bus format code that
depends on the sensor flips.

Grab the V4L2_CID_HFLIP and V4L2_CID_VFLIP controls on stream on, and
release on stream off to ensure flips cannot be changed while the sensor
is streaming.
