The i.MX51 and i.MX53 SoC device code still looks up the IIM with syscon_regmap_lookup_by_compatible(), though. Without the syscon fallback, syscon_node_to_regmap() cannot instantiate the regmap and boot reports: imx_soc_device_init: failed to find fsl,imx53-iim regmap! Restore the syscon fallback on i.MX51 and i.MX53.
