Aaron Durbin f56c7787ba google/chromeos: disable platform hierarchy on resume for TPM2 
On Chrome OS devices that use TPM2 parts the platform hierarchy
is disabled by the boot loader, depthcharge. Since the bootloader
isn't involved in resuming a suspended machine there's no equivalent
action in coreboot to disable the platform hierarchy. Therefore, to
ensure consistent state in resume the platform hierarchy in the TPM2
needs to be disabled as well. For systems that resume using the
firmware the platform hierarchy is disabled when utilizing
TPM2 devices.

BUG=chrome-os-partner:61097
BRANCH=reef
TEST=Suspend and resume. Confirmed 'stop trunksd; tpmc getvf; start
trunksd' shows that phEnable is 0.
