Series media: vimc: Add support for multiplanar formats | expand

Commit Message

André Almeida April 24, 2019, 1:56 p.m. UTC 
Define the pixelformat of the streamer depending to the
mode (single/multiplanar). Add a macro to help checking if the device is
in multilplanar mode.

Change in v3:
- Replace if with triaste operator

Change in v2:
- Add a macro to check if device is in multiplanar mode. Now, this check
is done using the capture device capabilities, rather than using the
multiplanar module parameter
