usb: UniPhier: add UniPhier on-chip EHCI host driver support
Support EHCI host driver used on Panasonic UniPhier platform.
Since Device Tree is not supported on UniPhier yet, the base address
of USB cores are passed from board files (platdevice.c).
TODO for me:
Move the base address to device trees.
