[PATCH v2] media: vimc: get pixformat info from v4l2_format_info

From: Carlos E. C. Barbosa
Date: Wed Jan 22 2020 - 03:40:38 EST


From: "Carlos E.C. Barbosa" <carlosecb@xxxxxxxxxxxx>

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

Signed-off-by: Carlos E. C. Barbosa <carlosecb@xxxxxxxxxxxx>
---
Changes in v2:
As advised by Helen Koike and Hans Verkuil, the const qualifiers are not
removed, the bayer flag is kept and the unnecessary changes are not
made.
