Maybe it's not necessary to separate the mtype from the get_vm_pte
function , so we just need one asic specific functions (get_vm_pte) .
What make me confusing originally is the the logic to setup the PTE
flag. We first map the UAPI flags to HW specific PTE flag , save it
into mapping structure and in amdgpu_bo_split_mapping adjust the
flag again before set the value to HW . Is it possible we just have one
place to set the asic specific PTE flag , ex, the mapping structure
still keep the UAPI flag and all the HW specific PTE setting is in the
last step before real set to HW ?
