In current code, when a PCI error state pci_channel_io_normal is detectd,
it will report PCI_ERS_RESULT_CAN_RECOVER status to PCI driver, and PCI
driver will continue the execution of PCI resume callback report_resume by
pci_walk_bridge, and the callback will go into amdgpu_pci_resume
finally, where write lock is releasd unconditionally without acquiring
such lock first. In this case, a deadlock will happen when other threads
start to acquire the read lock.
To fix this, add a member in amdgpu_device strucutre to cache
pci_channel_state, and only continue the execution in amdgpu_pci_resume
when it's pci_channel_io_frozen.

In the rare event when GFX IP suspend coincides with a s0ix entry, don't
schedule a delayed work, instead signal PMFW immediately to allow GFXOFF
entry. GFXOFF is a prerequisite for s0ix entry. PMFW needs to be
signaled about GFXOFF status before amd-pmc module passes OS HINT
to PMFW telling that everything is ready for a safe s0ix entry.

If you set amdgpu.discovery=2 you can force the the driver to
fetch the IP discovery table from a file rather than from the
table shipped on the device. This is useful for debugging and
for device bring up and emulation when the tables may be in flux.

Allow us to query instances versions more cleanly.
Instancing support is not consistent unfortunately. SDMA is a
good example. Sienna cichlid has 4 total SDMA instances, each
enumerated separately (HWIDs 42, 43, 68, 69). Arcturus has 8
total SDMA instances, but they are enumerated as multiple
instances of the same HWIDs (4x HWID 42, 4x HWID 43). UMC
is another example. On most chips there are multiple
instances with the same HWID. This allows us to support both
forms.
