USB: OHCI: make ohci-platform a separate driver

This patch splits the ohci-platform code from ohci-hcd out
into its own separate driver module.This work is part of enabling
multi-platform kernels on ARM.

In V2:
  -Passed "hcd" argument instead of "ohci" in ohci_setup() because it is
   using "struct usb_hcd" argument.
In V3:
  -Directly passed "hcd" argument not required to call ohci_to_hcd() function.
