[PATCH 1/6] media: uapi: Add MEDIA_BUS_FMT_SGRGB_IGIG_GBGR_IGIG media bus formats

[Marco Felsch]

Add special 8/12bit bayer media bus format for the OnSemi AR0237IR
camera sensor [1]. OnSemi calls this format RGB-IR, the pixel array
with the interleaved IR pixels looks like:

        |  G |  R |  G |  B | ...
        +----+----+----+----+---
        | IR |  G | IR |  G | ...
        +----+----+----+----+---
        |  G |  B |  G |  R | ...
        +----+----+----+----+---
        | IR |  G | IR |  G | ...
        +----+----+----+----+---
        | .. | .. | .. | .. | ..
