drivers/intel/fsp2_0: Make FSP Notify Phase APIs optional

The FSP API is used to notify the FSP about different phases in the
boot process. The current FSP specification supports three notify
phases:
 - Post PCI enumeration
 - Ready to Boot
 - End of Firmware

This patch attempts to make calling into the FSP Notify Phase APIs
optional by using native coreboot implementations to perform the
required lock down and chipset register configuration prior boot to
payload.

BUG=b:211954778
TEST=Able to build brya without any compilation issue and coreboot
log with this code changes when SKIP_FSP_NOTIFY_PHASE_READY_TO_BOOT
and SKIP_FSP_NOTIFY_PHASE_END_OF_FIRMWARE config enabled.

coreboot skipped calling FSP notify phase: 00000040.
coreboot skipped calling FSP notify phase: 000000f0.
