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
BUG=b:172279037
TEST=plug in USB keyboard while in S0, enter S0ix and verify entry via
EC; type on keyboard, verify it wakes up, eventlog contains:
39 | 2020-12-10 09:40:21 | S0ix Enter
40 | 2020-12-10 09:40:42 | S0ix Exit
41 | 2020-12-10 09:40:42 | Wake Source | PME - XHCI (USB 2.0 port) | 1
42 | 2020-12-10 09:40:42 | Wake Source | GPE # | 109
which verifies it still functions for the PCH XHCI controller
