drm/amd/display: Rename should_use_dmub_lock to reflect inbox1 usage

Browse source

[Why]
Newer DCN use the DMCUB HW lock via inbox0 for performance reasons while
older ones will use inbox1.

The should_use_dmub_lock() function does not describe whether the lock
in general should be used, but whether it should be used via inbox1.

[How]
Rename the function to should_use_dmub_inbox1_lock() to reflect this.
