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.
