Tvrtko Ursulin 6eadd448d7 drm/amdgpu: Choose SOC15 RLC register read write functions at init time 
Currently on every RLC register read the driver checks for three different
conditions to decide which of the two register read/write functions to
call.

As these register operations are macros, which is required for register
name expansion to work, the result is a significant explosion of generated
(redundant) code which the compiler cannot optimise away.

We however know that all of the three conditional are static and can
therefore move the decision to driver init time. All that we need to do is
define a new vfunc table for the SOC12 RLC read/write functions and just
use them directly.

Bloat-o-meter agrees the driver size savings are significant:

add/remove: 11/35 grow/shrink: 82/1117 up/down: 53024/-450922 (-397898)
...
Total: Before=10293928, After=9896030, chg -3.87%
