usb: chipidea: Fix ULPI on imx51
Workaround introduced for i.MX53 in be9cae2479f48 ("usb: chipidea: imx: Fix ULPI on imx53") seems to be applicable in case of i.MX51 as well. Running latest kernel on ZII RDU1 Board (imx51-zii-rdu1.dts) exhibits a kernel frozen on PORTSC access and applying the workaround resolves the issue.
