Subject: [PATCH] FROMLIST: media: pixfmt: Add Mediatek ISP P1 image & meta
 formats

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

(The current metadata format used in meta input and partial
meta nodes is only a temporary solution to kick off the driver
development and is not ready to be reviewed yet.)
