usb: musb: dsps: fix the base address for accessing the mode register
commit 943c13971c08 "usb: musb: dsps: implement ->set_mode()" should have made it possible to use the driver with boards that have the USBID pin unconnected. This doesn't actually work, since the driver uses the wrong base address to access the mode register. Furthermore it uses different base addresses in different places to access the same register (phy_utmi).
