Subject[PATCH v2 08/15] media: vimc: cap: Add multiplanar default format
Date
vimc already have a default single planar default format.
Add a multiplanar default pixel format to perform those
same actions. Change where the default pixelformat is set to make sure
that the vcap is with the right capabilities.

Signed-off-by: André Almeida <andrealmeid@collabora.com>

Change in v2:
- Move here the default format is set to verify if the device have a
multiplanar capability before assign the default format
