Since there are too many changes are done compare to your original
patch; i prefer keep a single patch,rather
keeping your original patch and my changes are another patch.

you need , ehci and ohci as a different hwmods, because later we can
add the mux to ehc and ochi independently.

This address space does not has sysconfig; so hwmod need not to map to
this address.
driver will to ioremap.

ports are not specific to usbhs or tll,  port 1 and port2  can be used
in phy or tll modes.
