soc/intel/alderlake: Avoid redundant chipset programming in romstage
This patch refactors the mainboard_romstage_entry() function to avoid
redundant chipset programming caused by global reset due to CSE FW
sync operation. Hence, keeping only the minimal and mandatory
operations required to perform CSE FW sync successfully.
This would help to optimize the boot flow by removing redundant
programming like SA, SMBUS twice in every CSE FW update path.
TEST=Able to build and boot Google/Marasov successfully.
