media: i2c: Add driver for Sony IMX662 sensor

This patch adds a V4L2 subdevice driver for the Sony IMX662 CMOS image
sensor. The sensor has a native resolution of 1936x1100 (effective
1920x1080) and can achieve up to 90 frames per second depending on
the configuration. The driver supports:
- MIPI CSI-2 with 2 or 4 data lanes.
- RAW10 and RAW12 formats (both colour and monochrome).
- Controls: exposure, analogue gain, horizontal/vertical blanking,
  horizontal/vertical flip, brightness.
- Runtime PM.
- Cropping via the selection API.
- Multiple link frequencies selectable via device tree.

Tested on ARM64 Rockchip RK3568 platform with a 24 MHz external clock
and various link frequencies.
