soc/intel/alderlake: Skip FSP Notify APIs
Alder Lake SoC deselects Kconfigs as below: - USE_FSP_NOTIFY_PHASE_READY_TO_BOOT - USE_FSP_NOTIFY_PHASE_END_OF_FIRMWARE to skip FSP notify APIs (Ready to boot and End of Firmware) and make use of native coreboot driver to perform SoC recommended operations prior booting to payload/OS. Additionally, created a helper function `heci_finalize()` to keep HECI related operations separated for easy guarding again config. TODO: coreboot native implementation to skip FSP notify phase API (post pci enumeration) is still WIP. BUG=b:211954778 TEST=Able to build brya with these changes and coreboot log with this code change as below when ADL SoC selects required configs. BS: BS_PAYLOAD_LOAD run times (exec / console): 135 / 62 ms coreboot skipped calling FSP notify phase: 00000040. coreboot skipped calling FSP notify phase: 000000f0. BS: BS_PAYLOAD_LOAD exit times (exec / console): 0 / 11 ms Finalizing chipset. apm_control: Finalizing SMM. APMC done.
