Problem:
After we start handling timed out jobs we assume there fences won't be
signaled but we cannot be sure and sometimes they fire late. We need
to prevent concurrent accesses to fence array from
amdgpu_fence_driver_clear_job_fences during GPU reset and amdgpu_fence_process
from a late EOP interrupt.
Fix:
Before accessing fence array in GPU disable EOP interrupt and flush
all pending interrupt handlers for amdgpu device's interrupt line.

Some initial settings now are not available from

In addition, driver needs to strictly follow

initialize parameters used to execute asic_init

According to my investigation of the state of PCI
reset recently it's not working. The reason is
due to the fact the kernel PCI code rejects SBR
when there are more then one PF under same bridge
which we always have (at least AUDIO PF but usually
more) and that because SBR will reset all the PFS
and devices under the same bridge as you and you
cannot assume they support SBR.
Once we anble FLR support we can reenable this option as
FLR is doable on single PF and doens't have this
restriction.

Evaluating `pcie_aspm_enabled` as part of driver probe has the implication
that if one PCIe bridge with an AMD GPU connected doesn't support ASPM
then none of them do. This is an invalid assumption as the PCIe core will
configure ASPM for individual PCIe bridges.
Create a new helper function that can be called by individual dGPUs to
react to the `amdgpu_aspm` module parameter without having negative results
for other dGPUs on the PCIe bus.

This patch handles the GPU recovery failure in sriov environment by
retrying the reset if the first reset fails. To determine the condition
of retry, a new macro AMDGPU_RETRY_SRIOV_RESET is added which returns
true if failure is due to ETIMEDOUT, EINVAL or EBUSY, otherwise return
false.A new macro AMDGPU_MAX_RETRY_LIMIT is used to limit the retry to 2.
It also handles the return status in Post Asic Reset by updating the return
code with asic_reset_res and eventually return the return code in
amdgpu_job_timedout().

now and so needs to be present as long as each device
in a hive needs it and so it cannot be binded to XGMI

Adress this by making reset domain refcounted and pointed

v4:
Fix crash on boot witrh XGMI hive by adding type to reset_domain.
XGMI will only create a new reset_domain if prevoius was of single
