drm/amd/amdgpu: Fix the mes version that support inv_tlbs

Browse source

MES pipe0 will do VM invalidation with engine set 5 when assign VMID to a process,
driver will submit inv_tlb package to mes pipe1. It might run into race condition
if both pipes use the same invalidate engine set. From MES version 0x83 it will use
invalidate engine set 6 for pipe1 to fix the issue
