Series CSI2RX support on J721E and AM62 |

  Multiple TI SoCs (J721E, AM62) use this CSI2RX receiver, integrated with
an external DPHY and a pixel-grabber IP that unwraps the pixel data and
send it to memory via DMA.

Add a separate compatible for the TI-specific version of this IP.

Why do you need it? It's redundant - already compatible with cdns. No
need to add empty match entries.

Hi Krzysztof,

Thanks for the review.

Understood, will drop this patch in the next revision and re-introduce 
later whenever we add something SoC specific in the driver.
