Hello,

This small series improves conversion between DRM and V4L2 formats, to
pave the way to adding more format information in the libcamera core.

Patch 1/4 starts by moving the V4L2PixelFormat class to a separate file,
without modifying the code. Patch 2/4 then moves format conversion from
V4L2VideoDevice to V4L2PixelFormat, and patch 3/4 replaces the big
switch-case's with std::map. Patch 4/4 finally adds support for
MIPI-packed 10-bit Bayer formats.
