usb: chipidea: Fix ULPI on imx51

Browse source 
Workaround introduced for i.MX53 in be9cae2479 ("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.
