USB: ehci_fsl update for MPC831x support
For MPC831x support, change the ehci-fsl driver to preserve
bits set in platform code. Add a common CONFIG_USB_EHCI_FSL
to indicate presence of Freescale EHCI SOC. Add FSL_USB2_DR_OTG
operating mode support, thus both host and device can work for the
mini-ab receptacle. Note: this doesn't enable OTG protocol
support.
