Unify how we map the UAPI flags to the PTE hardware flags for a mapping.
Only the MTYPE is actually ASIC dependent, all other flags should be
copied over 1 to 1 and ASIC differences are handled later on.

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 ?

I thought about that approach as well, but that would unfortunately not work correctly. The problem is that we have some mapping flags which don't have an userspace representation. Additional to that I want to avoid leaking the UAPI defines into the VM subsystem. We shouldn't have created the UAPI defines in the first place and should have used the hardware flags directly.

Only the MTYPE is actually ASIC dependent, all other flags should be copied over 1 to 1 and ASIC differences are handled later on.
