Dinh Nguyen 5a25ad84e0 mxc: Add generic USB HW initialization for MX51
This patch adds USB HW initializiation code to /plat-mxc/ehci.c.
	-Sets some specific PHY settings
Renames mxc_set_usbcontrol to mxc_initialize_usb_hw.
Adds new register bit defines for the USB HW on Freescale
SoCs.

This patch applies to 2.6.34-rc6.
