add corrupt and reload options to 'ec_comm' console cmd
Two new options for 'ec_comm' are for test usage only.
- ec_comm corrupt: it corrupts the ECRW hash in ec_comm module.
Hash corruption will cause EC-FW verification failure. It can be
useful to check how AP firmware performs software sync on this
failure.
- ec_comm reload: it forces Cr50 to reload ECRW hash from tpm nvmem.
This is to restore the EC EFS2 status in Cr50 from corrupted status.
BUG=b:150650877
BRANCH=cr50
TEST=manually ran 'ec_comm corrupt' or 'ec_comm reload' with dev image.
Checked cr50 normal image refuses those command lines.
