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 hypervisor(host) MONITOR-WAIT support and refine
software sram initializaion flow.

Current implementation, SOS may allocate the memory region belonging to
hypervisor/pre-launched VM to a post-launched VM. Because it only verifies
the start address rather than the entire memory region.
This patch verifies the validity of the entire memory region before
allocating to a post-launched VM so that the specified memory can only
be allocated to a post-launched VM if the entire memory region is mapped
in SOS’s EPT.

Software SRAM region.
- Refine parse_rtct() function, validity of
ACPI RTCT table shall be checked by caller.

Physical address to SW SRAM region maybe different
on different platforms, this hardcoded address may
result in address mismatch for SW SRAM operations.
This patch removes above hardcoded address and uses
the physical address parsed from native RTCT.

'ptcm' and 'ptct' are legacy name according
to the latest TCC spec, hence rename below files
to avoid confusing:
ptcm.c -> rtcm.c
ptcm.h -> rtcm.h
ptct.h -> rtct.h
