Given we can query all the asic specific information from amdgpu_gfx_config,
we can make get_tile_config() generic.

[Why]
kfd2kgd interface will be deprecated. This removal only covers TLB
invalidation for now. They have been replaced in amdgpu_amdkfd API.
[How]
TLB invalidate functions removed from the different amdkfd_gfx_v*
versions.

get_atc_vmid_pasid_mapping_valid() is very similar to
get_atc_vmid_pasid_mapping_pasid(), so they can be merged into a new
function get_atc_vmid_pasid_mapping_info() to reduce register access
times. More importantly, getting the PASID and the valid bit atomically
with a single read fixes some potential race conditions where the
mapping changes between the two reads.

The old name is prone to confusion. The register offset is for a RLC queue
rather than a SDMA engine. The value is not a base address, but a

Method of getting firmware version is the same across ASICs, so remove

Such VMs get destroyed when the original file descriptor is released.

Add wptr and mm parameters to hqd_sdma_load and pass these parameters
from device_queue_manager through the mqd_manager.
SDMA doesn't support polling while the engine believes it's idle. The
driver must update the wptr. The new parameters will be used for looking
up the updated value from the specified mm when SDMA queues are resumed
after being disabled.

Allows assigning a PASID to a VM for identifying VMs involved in page
faults. The global PASID manager is also exported in the KFD
interface so that AMDGPU and KFD can share the PASID space.
PASIDs of different sizes can be requested. On APUs, the PASID size
is deterined by the capabilities of the IOMMU. So KFD must be able
to allocate PASIDs in a smaller range.
