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 interface 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.)

+8-bit Packed Bayer formats.

+Description
+===========
+
+The four pixel formats are used by Mediatek ISP.
+This is a packed format, meaning all the data for a pixel lie
+next to each other in memory, with a depth of 8 bits per pixel.
+Each sample is stored in a byte.
+The least significant byte is stored at lower memory addresses (little-endian).
+The RGB byte order follows raw sRGB / Bayer format from sensor.
+Below is an example of conventional RGB byte order BGGR.
+
+**Byte Order.**
+Each cell is one byte.

+14-bit Packed Full-G Bayer formats.
+
+
+Description
+===========
+
+The four pixel formats are used by Mediatek ISP.
+This is a packed format with a depth of 14 bits per pixel.
+Full-G means 1 more pixel for green channel every 2 pixels.
+The least significant byte is stored at lower memory addresses (little-endian).
+The RGB byte order follows raw sRGB / Bayer format from sensor.
+Below is an example of conventional RGB byte order BGGR.
