56fcfb5b4f 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

Add support to check for the Power Management (PM) Status bit for
various internal devices like USB, CNVi etc. and log them into the event
log for debugging purposes.

BUG=b:172279037
TEST=Build and boot to OS in Drawlat. Ensure that the wake up event is
logged into the event log for one of the internal devices eg. USB
bluetooth.
