[PATCH] media: vpif: use a configurable i2c_adapter_id for vpif display

[Bartosz Golaszewski]

The vpif display driver uses a static i2c adapter ID of 1 but on the
da850-evm board in DT boot mode the i2c adapter ID is actually 0.

Make the adapter ID configurable like it already is for vpif capture.

Hi Mauro, Prabhakar,

can we get an ack on this? Sekhar already merged the rest of the
patches that need this to make vpif display work on the da850-evm
board. I think it's best if it goes through his tree.

Thanks,
Bartosz

Thanks!

Sekhar let me know, that this should be picked up by media. Also:
there are still two DT bindings patches for vpif that can be picked up
- Rob Herring acked them.

Thanks,
Bartosz
