This patch implements the required operations to perform prior to
booting to OS using coreboot native driver when platform decides
to skip FSP notify APIs i.e. Post PCI Enumeration.
The smbus `.final` operation ensures locking the TCO register when
coreboot decides to skip FspNotifyApi() calls.
BUG=b:211954778
TEST=Able to build google/brya with these changes and coreboot log with
this code change as below with ADL SoC skip calling into FspNotifyAPIs:
[INFO ] Finalize devices...
[DEBUG] PCI: 00:1f.4 final
> localhost ~ # lspci -xxx | less
00:1f.4 Intel Corporation Alder Lake PCH-P SMBus Host Controller
(rev 01)
Offset 8, Bit 12 a.k.a TCO Lock bit is set (meaning locked).
