drm/amd/display: isolate global double buffer lock programming
[why]
Global optic double buffer lock is currently disabled due to
incorrect programming sequence that affects non global lock.
[how]
Isolate global lock programming sequence out of non global lock
programming sequence, so it can be enabled without affecting
non global lock.
