Update drm_of_get_data_lanes_count_ep() return value documentation
to match the drm_of_get_data_lanes_count() return value documentation.
The drm_of_get_data_lanes_count_ep() is only a wrapper around the
drm_of_get_data_lanes_count() and therefore returns the same error
codes.
Fixes: fc801750b197 ("drm: of: Add drm_of_get_data_lanes_count and
drm_of_get_data_lanes_ep")
