[PATCH v2 4/4] usb: chipidea: usbmisc_imx: Add prefix to register defines

The driver is used for a broad range of i.MX SoCs and most of the
register defines have a SoC/regname specific prefix to make clear
in which context they should be used. Add such a prefix to the
MX7D_USB_OTG_PHY_CFG1 defines as well.
