soc/intel/alderlake: Perform `soc_finalize` at entry of BS_PAYLOAD_BOOT

This patch ensures soc_finalize() is getting called at the entry of
BS_PAYLOAD_BOOT boot state instead of BS_PAYLOAD_LOAD, BS_ON_EXIT.

The purpose of this change is to accommodate more time to push out
sending CSE EOP messages at post.

BUG=b:200644229
TEST=coreboot serial log suggests soc_finalize() is getting called
as part of the BS_PAYLOAD_BOOT entry.

Finalizing chipset.
apm_control: Finalizing SMM.
APMC done.
BS: BS_PAYLOAD_BOOT entry times (exec / console): 21 / 15 ms
