tpm2: add extension command for immediate reset
Cr50 updates in development environment should allow resetting the
device immediately after update (without the need for SYS_RST_L to be
toggled).
This patch adds a vendor command to do just that.
BRANCH=none
BUG=chrome-os-partner:60013. chrome-os-partner:60321
TEST=none yet, with the rest of the patches applied the target gets
rebooted immediately after a cr50 code update. Also, observed
that flashing the console does not quite work, opend
crosbug.com/p/60321 to address this.
