However, we don't have a working driver for RFBI, so if RFBI device exists, omapdss will never get probed. All the .dtsi files set RFBI as disabled, except am4372.dtsi. This causes omapdss probe to not finish on AM4 devices. This patch makes omapdss driver skip adding rfbi device as a subcomponent, solving the issue. This should be reverted when we have a working RFBI driver.
