soc/intel/common: Adapt XHCI elog driver for reuse

Currently this XHCI driver assumes the PCH XHCI controller, but the TCSS
or North XHCI block has a similar enough PCI MMIO structure to make this
code mostly reusable.

1) Rename everything to drop the `pch_` prefix
2) xhci_update_wake_event() now takes in a pci_devfn_t for the XHCI
controller
3) soc_get_xhci_usb_info() also now takes a pci_devfn_t for the XHCI
controller
