Nicholas Kazlauskas f1029e7ead drm/amd/display: Avoid NULL pointer in set_backlight when ABM is NULL 
[Why]
On ASIC without ABM support (most dGPU) we run into a null pointer
dereference when attempting to set the backlight level.

[How]
This function requires ABM, so fix up the condition to only allow
DMCU to be optional.
