mb/google/guybrush: Set TPM to to be kernel power managed.

Set TPM power_managed_mode to TPM_KERNEL_POWER_MANAGED. This will cause
the TPM kernel driver to send a shutdown command before s0i3 entry. This
change depends on S0i3 verstage running and reinitializing the TPM.

BUG=b:200578885
BRANCH=None
TEST=TPM shutdown sent during s0i3 entry on guybrush
