drm/amd/display: register edp_backlight_control() for DCN301
As made mention of in commit 099303e9a9bd ("drm/amd/display: eDP intermittent black screen during PnP"), we need to turn off the display's backlight before powering off an eDP display. Not doing so will result in undefined behaviour according to the eDP spec. So, set DCN301's edp_backlight_control() function pointer to dce110_edp_backlight_control().
