+ Required properties:
+ - compatible : should be "fsl,<chip>-qe-usb", "fsl,mpc8323-qe-usb";
+ - reg : the first two cells should contain gtm registers location and
+ length, the next two two cells should contain PRAM location and
+ length.
+ - interrupts : should contain USB interrupt.
+ - interrupt-parent : interrupt source phandle.
+ - fsl,fullspeed-clock : specifies the full speed USB clock source in
+ "clk<num>" or "brg<num>" format.
+ - fsl,lowspeed-clock : specifies the low speed USB clock source in
+ "clk<num>" or "brg<num>" format.
+ - fsl,usb-mode : should be "host".
+ - linux,hub-power-budget : optional, USB power budget for the root hub
+ in mA.
+ - gpios : should specify GPIOs in this order: USBOE, USBTP, USBTN, USBRP,
