[PATCH RFC 3/4] media: i2c: imx678: Add imx662 support to the driver

[Dave Stevenson <dave.stevenson@raspberrypi.com>]

IMX662 is a 1080p Starvis 2 sensor that follows the same programming
pattern as IMX678, so add it to the newly parameterised driver.

FIXME: Update the common registers based on the Sony spreadsheet.
