ec_sync: Run EFS2 in romstage
EFS2 allows EC RO to enable PD for special cases. When doing so, it sets
NO_BOOT flag to avoid booting the OS. AP needs to get NO_BOOT flag from
Cr50 and enforce that.
This patch makes verstage get a boot mode and a mirrored hash stored
in kernel secdata from Cr50.
This patch also makes romstage write an expected EC hash (a.k.a. Hexp) to
Cr50 (if there is an update).
