[PATCH 00/14] gpu soft reset patches V2

[Chunming Zhou]

The series is to add gpu soft reset:
Check gpu status first, if MC/VMC/DISPLAY hang, directly triger full reset.
If engine hangs, then triger engine soft reset, if soft reset fails, will
fallback to full reset.

V2: use per ip block soft reset

tests:
gfx and sdma engines are tested successfully by soft reset on Fiji.
