this lock is used for sriov_gpu_reset, only get this mutex
can run into sriov_gpu_reset.
we have couple source triggers gpu_reset for SRIOV:
1) submit timedout and trigger reset voluntarily
2) invalid instruction detected by ENGINE and trigger reset voluntarily
2) hypervisor found world switch hang and trigger flr and notify guest to
do reset.
all need take care and we need a mutex to protect the consistency of
reset routine.

bo_va is being kfree'd twice, once in the call to amdgpu_vm_bo_rmv
and then a short while later. Fix this double free by removing
the 2nd kfree.

Add high level interfaces that is not relate to specific asic. So
asic files just need to implement the interfaces to support
virtualization.

for SRIOV usage, CSA is only used per device and each
