USB: UHCI: Wrap I/O register accesses

This patch is part of a series that extend the UHCI HCD to support
non-PCI controllers.

This patch replaces in{b,w,l} and out{b,wl} with calls to local inline
functions. This is done so that the register access functions can be
extended to support register areas not mapped in PCI I/O space.
