Magnus Damm 526c1c23a2 sh: fix USBF resource for sh7722
The USBF function on sh7722 is currently not working with the m66592_udc
driver. The driver is using platform_get_resource_byname() so my commit
a0d29798e5 broke sh7722 support.

The long term fix is to replace platform_get_resource_byname() in the
driver with platform_get_resource(), but this helps until that happens.
