aco: add TBA/TMA/TTMP0-11 physical registers definitions

The TBA/TMA scalar registers are only available on GFX6-GFX8.

On GFX9+, TBA/TMA addr are stored in hardware registers and
the number of TTMP scalar registers is thus increased by 4.
Just keep in mind that tba_lo is actually ttmp0. Best would
be to support ttmp registers in RA but that's more complicated.
