drm/amd/display: Fix AMDGPU_MAX_BL_LEVEL value
commit 66abb996999de0d440a02583a6e70c2c24deab45 upstream.
[Why]
commit 16dc8bc27c2a ("drm/amd/display: Export full brightness range to
userspace") adjusted the brightness range to scale to larger values, but
missed updating AMDGPU_MAX_BL_LEVEL which is needed to make sure that
scaling works properly with custom brightness curves.
[How]
As the change for max brightness of 0xFFFF only applies to devices
supporting DC, use existing DC define MAX_BACKLIGHT_LEVEL.
Fixes: 16dc8bc27c2a ("drm/amd/display: Export full brightness range to userspace")
