powerpc/512x: dts: disable MPC5125 usb module
At the moment the USB controller's pin muxing is not setup correctly and causes a kernel panic upon system startup, so disable the USB1 device tree node in the MPC5125 tower board dts file. The USB controller is connected to an USB3320 ULPI transceiver and the device tree should receive an update to reflect correct dependencies and required initialization data before the USB1 node can get re-enabled.
