[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.

This is the same idea as the kfd device info probe and move all the
probe control together for easy maintenance.

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
register offset.

Calling amdgpu function to invalidate TLB, instead of using a
kfd implementation. Delete the kfd local TLB invalidation
implementation.
