drm/amd/display/amdgpu_dm: Add a bl_idx to amdgpu_dm_connector
Currently functions like update_connector_ext_caps() and
amdgpu_dm_connector_destroy() are iterating over dm->backlight_link[i]
to find the index of the (optional) backlight_dev associated with
the connector.
Instead make register_backlight_device() store the dm->backlight_dev[]
index used for the connector inside the amdgpu_dm_connector struct.
This removes the need to iterate over the dm->backlight_link[]
array and this is necessary as a preparation patch for moving
the actual backlight_device_register()
call to drm_connector_funcs.late_register.
While reworking update_connector_ext_caps() also remove the aconnector
and aconnector->dc_link NULL checks in this function. These are both
never NULL and are unconditionally derefed in its callers.
