Also removing the call to amdgpu_atombios_encoder_get_backlight_level_from_reg()
since, according to Alex Deucher, "We call it again below indirectly".

Fixes the following W=1 kernel build warning(s):

 drivers/gpu/drm/amd/amdgpu/atombios_encoders.c: In function ‘amdgpu_atombios_encoder_init_backlight’:
 drivers/gpu/drm/amd/amdgpu/atombios_encoders.c:174:5: warning: variable ‘backlight_level’ set but not used [-Wunused-but-set-variable]
