drm/amdgpu: Fix crash on device remove/driver unload
Crash:
BUG: unable to handle page fault for address: 00000000000010e1
RIP: 0010:vega10_power_gate_vce+0x26/0x50 [amdgpu]

Why:
VCE/UVD had dependency on SMC block for their suspend but
SMC block is the first to do HW fini due to some constraints
How:
Since the original patch was dealing with suspend issues
move the SMC block dependency back into suspend hooks as
was done in V1 of the original patches.
Keep flushing idle work both in suspend and HW fini seuqnces
since it's essential in both cases.
Fixes: 859e4659273f1d ("drm/amdgpu: add missing cleanups for more ASICs on UVD/VCE suspend")
Fixes: bf756fb833cbe8 ("drm/amdgpu: add missing cleanups for Polaris12 UVD/VCE on suspend")
