cpu/intel/car: Add EC software sync to Intel romstage

Perform EC software sync in romstage, before memory training is started.
This is guarded by CONFIG_VBOOT_EARLY_EC_SYNC.

BUG=b:112198832
BRANCH=none
TEST=EC software sync works in update and non-update case.
No significant effect on boot time (~6 ms).
