mb/google/volteer: Disable HybridStorageMode for volteer baseboard

HybridStorageMode FSP UPD needs to be set only for optane storage.
Enabling HybridStorageMode causes some extra delay in FspSiliconInit due
to HECI command and hence is avoided for NVMe and SATA scenerios. This
change disables "HybridStorageMode" for volteer baseboard. For boards
using optane HybridStorage needs to be enabled from overwrite devicetree.

BUG=b:158573805
TEST=Build and boot non optane device and confirm that FspSiliconInit
time is reduced. This saves ~100ms.
