This reverts commit a518c746510e03d8a78db432a659770182546b9e.
Reduce the time we wait since we are waiting for the

[Why]
Under SR-IOV, we are not sure whether pipe status is
good or not when doing initialization. The compute engine
maybe fail to bringup if pipe status is bad.
[How]
For SR-IOV, disable the compute engine to do a pipe reset
before we do initialization.

[Why]
Under SR-IOV, if VF is switched out then its doorbell will be disabled,
SDMA rely on WPTR_POLL to get doorbells which was sent during VF
switched-out time.
[How]
For SR-IOV, set SDMA WPTR_POLL_ENABLE to 1.

So create a new function in amdgpu_virt to check whether FW load needs

[Why]
This WPTR_POLL_ENABLE is a hardware contigious polling which will cause
FCLK and UCLK to keep on a high level.
Mostly its case can be covered by F32_WPTR_POLL_ENABLE which polls by
firmware.
So to save power, SR-IOV also needs to disable this bit

VCN will use some framebuffer space as its cache. It needs to
be reset when reset happens, such as FLR. Otherwise some error
may be kept after the reset.
