media: i2c: add driver for ITE IT6625/IT6626
Add a V4L2 subdevice driver for the ITE IT6625/IT6626 HDMI-to-MIPI
CSI-2 bridge chips. IT6625 accepts an HDMI 2.0 input and IT6626 an
HDMI 2.1 input, converting it to a D-PHY (or C/D-PHY on IT6626)
MIPI CSI-2 output. The bridge is configured over I2C, exposes an
HDMI CEC adapter, and supports EDID read/write, DV timings
detection/configuration, and HPD control via the standard V4L2
subdevice pad and video ops.
