The following patch reorganizes/reworks the USB support for mpc83xx
as under:-
* Moves the 83xx USB clock init from drivers/usb/host/ehci-fsl.c to
cpu/mpx83xx/cpu_init.c
* Board specific usb_phy_type is read from the environment
* Adds USB EHCI specific structure in include/usb/ehci-fsl.h
* Copyrights revamped in most of the following files
