soc/intel/apollolake: Disable HECI2 device reset on S3 resume
Converged Security Engine (CSE) has a secure variable storage feature.
However, this storage is expected to be reset during S3 resume flow.
Since coreboot does not use secure storage feature, disable HECI2 reset
request. This saves appr. 130ms of resume time.
BUG=chrome-os-partner:56941
BRANCH=none
TEST=powerd_dbus_suspend; resume; check time with cbmem -t. Note
FspMemoryInit time is not significantly different from normal boot
time case.
