USB: UHCI: Allow dynamic assignment of bus specific functions
This patch is part of a series that extend the UHCI HCD to support
non-PCI controllers.
This patch changes calls to uhci_reset_hc, uhci_check_and_reset_hc,
configure_hc, resume_detect_interrupts_are_broken and
global_suspend_mode_is_broken so that they are made through pointers
in the uhci hcd struct. This will allow these functions to be replaced
with bus/arch specific functions.
