VFs do not perform HW fini/suspend in FLR, so the dpm_enabled
is incorrectly kept enabled. Add interface to disable it in
virt_pre_reset call.
v2: Made implementation generic for all asics
v3: Re-order conditionals so PP_MP1_STATE_FLR is only evaluated on VF

[Why]
If VF request full GPU access and the request failed,
the VF driver can get stuck accessing registers for an extended period during
the unload of KMS.
[How]
Set no_hw_access flag when VF request for full GPU access fails
This prevents further hardware access attempts, avoiding the prolonged
stuck state.

We send back the ready to reset message before we stop anything. This is
wrong. Move it to when we are actually ready for the FLR to happen.
In the current state since we take tens of seconds to stop everything,
it is very likely that host would give up waiting and reset the GPU
before we send ready, so it would be the same as before. But this gets
rid of the hack with reset_domain locking and also let us tell how slow
ready to reset actually is from the host. The ready to reset speed can
be improved later.

Flag "mes.ring.shced.ready" will be set as true after mes hw init and set
as false when mes hw fini to avoid duplicate initialization. But hw fini
will not be called when function level reset, which will cause mes hw
init be skipped during FLR, which will leads to mapping legacy queue
fail. Set this flag as false when post reset will fix this issue.

Some times a hang GPU causes multiple reset sources to schedule resets.
The second source will be able to trigger an unnecessary reset if they
schedule after we call amdgpu_device_stop_pending_resets.
Move amdgpu_device_stop_pending_resets to after the reset is done. Since
at this point the GPU is supposedly in a good state, any reset scheduled
after this point would be a legitimate reset.
Remove unnecessary and incorrect checks for amdgpu_in_reset that was
kinda serving this purpose.

[Why]
Regression of commit 72fef4980ddf ("drm/amdgpu: Remove writing GRBM_GFX_CNTL in RLCG interface under SRIOV") on GFX9.
According to GFX9 VF using different method to access GC registers including MMIO(direct) and RLCG(indirect),
removing GRBM_GFX_* writing would make PIPE/ME/VM/QUEUE selection chaos leading to some OCL benchmark failure.
For example,
using RLCG interface to program GRBM_GFX_CNTL/INDEX for selecting MEC(actually the value is only in scratch2/3),
then using MMIO directly program a MEC register in VF driver.
The register programming are invalid due to GC switched to incorrect ME.
[How]
With checking RLCG accessing flag, keep writing GRBM_GFX_* as a legacy way.
But it is still skipped on GFX10+ to avoid violation occurrence.

[Why]
Accessing GRBM_GFX_CNTL in full access time has risk when VF is doing MMIO attacking.
Therefore, VF writing GRBM_GFX_CNTL are blocked by L1 Policy.
For RLCG interface, RLCG use SCRATCH_REG2 which is copied from GRBM_GFX_CNTL.
[How]
Remove writing GRBM_GFX_CNTL in amdgpu_virt_rlcg_reg_rw.

While technically Xen dom0 is a virtual machine too, it does have

"passthrough". Commit b818a5d37454 ("drm/amdgpu/gmc: use PCI BARs for
APUs in passthrough") changed how FB is accessed based on passthrough
mode. This breaks amdgpu in Xen dom0 with message like this:
[drm:dc_dmub_srv_wait_idle [amdgpu]] *ERROR* Error waiting for DMUB idle: status=3
While the reason for this failure is unclear, the passthrough mode is
not really necessary in Xen dom0 anyway. So, to unbreak booting affected
kernels, disable passthrough mode in this case.
