14-bit Packed Bayer formats.

Description
===========

These four pixel formats are used by Mediatek ISP P1.
This is a packed format, meaning all the data bits for a pixel lying
next to each other with no padding in memory, with a depth of 14 bits per pixel.
The least significant byte is stored at lower memory addresses (little-endian).
The RGB byte order follows raw sRGB / Bayer format from sensor.
They are conventionally described as GRGR... BGBG..., RGRG... GBGB..., etc.
Below is an example of conventional RGB byte order BGGR.

**Byte Order.**
Each cell is one byte.

pixels cross the byte boundary and have a ratio of 7 bytes for each 4 pixels.
