drm/amd/display: Fix programming backlight on OLED panels
commit 38077562e059 ("drm/amd/display: Implement new
backlight_level_params structure") adjusted DC core to require
the backlight type to be programmed in the dc link when changing
brightness. This isn't initialized in amdgpu_dm for OLED panels
though which broke brightness.
Explicitly initialize when aux support is enabled.
