ARM: cns3xxx: Add architecture definition for EHCI/OHCI controller

This patch add plateform_device for EHCI and OHCI controller on CNS3XXX.
Power reference count (usb_pwr_ref) is used to control enabling and
disabling the single clock control for both EHCI and OHCI controller.

It also removes EHCI/OHCI unused virtual address definitions.
