media: imx274: add helper to read multibyte registers
Currently 2-bytes and 3-bytes registers are read one byte at a time,
doing the needed shift & mask each time.
Replace all of this code by a unique helper function that calls
regmap_bulk_read(), which has two advantages:
- reads all the bytes in a unique I2C transaction
- simplifies code to read multibyte registers
