[PATCH v4 26/34] media: camss: Format configuration per hardware version

From: Todor Tomov
Date: Wed Jul 25 2018 - 12:39:55 EST

As the 8x16 and 8x96 support different formats, separate the
arrays which contain the supported formats. For the VFE also
add separate arrays for RDI and PIX subdevices.
