Subject: [PATCH v4 00/10] media: imx-jpeg: Add support for 12 bit extended jpeg

the imx8 jpeg codec support ISO/IEC 10918-1 Standard Baseline and
Extended Sequential DCT modes.
it can support 8-bit and 12-bit per color samples.
Currently we only enable the 8-bit jpeg,
and we can enable the 12-bit extended jpeg
with the new defined 12 bit pixel format.

v4
- drop format yuyv64_12, use Y212 directly

v3
- correct the new 12-bit format naming according to Nicolas's comments

v2
