Platform specific code for MPC5121 USB Host support. MPC5121 Rev 2.0 silicon EHCI registers are big endian. Add appropriate support by specifying "fsl,big-endian-regs" property in device tree node for USB controller. Also allow specifying DRVVBUS and PWR_FAULT signal polarity of the MPC5121 internal PHY using "fsl,invert-drvvbus" and "fsl,invert-pwr-fault" properties.
