Yonghua Huang 1a011bd91b hv: disable guest MONITOR-WAIT support when SW SRAM is configured 
Per-core software SRAM L2 cache may be flushed by 'mwait'
extension instruction, which guest VM may execute to enter
core deep sleep. Such kind of flushing is not expected when
software SRAM is enabled for RTVM.

Hypervisor disables MONITOR-WAIT support on both hypervisor
and VMs sides to protect above software SRAM from being flushed.

This patch disable ACRN guest MONITOR-WAIT support if software
SRAM is configured.
