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.
