soc/intel/elkhartlake: Skip FSP Notify APIs
Follow this commit 95986169f (soc/intel/alderlake: Skip FSP Notify APIs)
to skip FSP Notify APIs.
Elkhart 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.
When deselecting these Kconfigs, cse_final_ready_to_boot() and
cse_final_end_of_firmware() in the common cse driver will be used
instead as required operations to perform prior to booting to OS.
Check out this CL for further info:
commit 90e318bba (soc/intel/common/cse: Add `finalize` operation for
CSE)
Additionally, create a helper function `heci_finalize()` to keep HECI
related operations separated for easy guarding again config.
