[RFC V1 07/12] media: platform: Add Mediatek ISP P1 image & meta formats

[Jungo Lin <jungo.lin-NuS5LvNUpcJWk0Htik3J/w@public.gmane.org>]

Add packed/unpacked/full-g bayer format with 8/10/12/14 bit
for image output. Add Pass 1 (P1) specific meta formats for
parameter processing and 3A/other statistics.
