soc/amd/cezanne: Add support to perform early EC sync
Ideally we would like to perform EC Software Sync in payload. But with
the hardware requirement (EC_IN_RW) and firmware requirement (TPM
command to get EC execution environment) not met yet, adding the support
to perform early EC Software sync. With EFS2 enabled, this will also
help cr50 to set the boot mode as NORMAL instead of NO_BOOT.
BUG=None
TEST=Build and Boot to OS in Guybrush. Ensure that the EC software sync
is successfully complete.
