drm/amd/display: fix B0 TMDS deepcolor no dislay issue

[why]
B0 PHY C map to F, D map to G driver use logic instance, dmub does the
remap. Driver still need use the right PHY instance to access right HW.

[how]
use phyical instance when program PHY register.

[note]
could move resync_control programming to dmub next.
