[PATCH 14/73] drm/amdgpu/gfx10: use INVALIDATE_TLBS to invalidate TLBs v2

[Alex Deucher]

From: Jack Xiao <Jack.Xiao at amd.com>

For MES queue VM flush, use INVALIDATE_TLBS to invalidate TLBs.
This packet can let CP firmware to determine the current vmid
and inv eng to invalidate.

v2: unify invalidate_tlbs functions
