drm/amd/display: Only read ACPI backlight caps once
commit ffcaed1d7ecef31198000dfbbea791f30f7ca437 upstream.
[WHY]
Backlight caps are read already in amdgpu_dm_update_backlight_caps().
They may be updated by update_connector_ext_caps(). Reading again when
registering backlight device may cause wrong values to be used.
[HOW]
Use backlight caps already registered to the dm.
