Hi,

This is the first version of RFC patch for Media Data Path 3 (MDP3),
MDP3 is used for scaling and color format conversion.
support using GCE to write register in critical time limitation.
support V4L2 m2m device control.

Changes since v1:
- modify code for CMDQ v3 API support
- EC ipi cmd migration
- fix compliance test fail item (m2m cmd with -f)
due to there is two problem in runing all format(-f) cmd:
1. out of memory before test complete
	Due to capture buffer mmap (refcount + 1) after reqbuf but seems
	no corresponding munmap called before device close.
	There are total 12XX items(formats) in format test and each format
	alloc 8 capture/output buffers.
2. unceasingly captureBufs() (randomly)
	Seems the break statement didn't catch the count == 0 situation:
	In v4l2-test-buffers.cpp, function: captureBufs()
			...
			count--;
			if (!node->is_m2m && !count)
				break;
	Log is as attachment

I will paste the test result with problem part in another e-mail
