drm/radeon: use callbacks for ring pointer handling (v3) 

Add callbacks to the radeon_asic struct to handle
rptr/wptr fetchs and wptr updates.
We currently use one version for all rings, but this
allows us to override with a ring specific versions.

Needed for compute rings on CIK.

v2: udpate as per Christian's comments
v3: fix some rebase cruft
