[PATCH v5] media: vimc: get pixformat info from v4l2_format_info

From: Carlos E. C. Barbosa

There is overlapping code over two distinct lists. This repurposes
vimc_pix_map for mapping formats and remaps the calls to the matching
v4l2_format_info.

Signed-off-by: Carlos E. C. Barbosa <barbosa.carlos.ec@xxxxxxxxx>

Changes in v5:
- .bayer member was removed and replaced by v4l2 functions calls

Changes in v4:
- Unused variables were removed

Changes in v3:
- Change declaration order of variables and some minor style changes

Changes in v2:
- Const qualifiers are not removed
- Bayer flag is kept
- Unnecessary changes are not made anymore

v4l2-compliance -m /dev/media0 output:
