Add support for clean shutdown of the root partition when running on MSHV
hypervisor.

v3:
- Dropped acpi_sleep handlers as they are not used on mshv
- Applied ordering for hv_reboot_notifier
- Fixed build issues on i386, arm64 architectures

v2:
- Addressed review comments from v1.
- Moved all sleep state handling methods under CONFIG_ACPI stub
- - This fixes build issues on non-x86 architectures.

Praveen K Paladugu (2):
hyperv: Add definitions for MSHV sleep state configuration
hyperv: Enable clean shutdown for root partition with MSHV
