Qi Yadong 3ebeecf060 hv: save/restore TSC in host's suspend/resume path
TSC would be reset to 0 when enter suspend state on some platform.
This will fail the secure timer checking in secure world because
secure world leverage the TSC as source of secure timer which should
be increased monotonously.

This patch save/restore TSC in host suspend/resume path to guarantee
the mono increasing TSC.

Note: There should no timer setup before TSC resumed.

ACRN Hypervisor
###############

The open source `Project ACRN`_ defines a device hypervisor reference stack and
an architecture for running multiple software subsystems, managed securely, on
a consolidated system by means of a virtual machine manager. It also defines a
reference framework implementation for virtual device emulation, called the
"ACRN Device Model".

The ACRN Hypervisor is a Type 1 reference hypervisor stack, running directly on
the bare-metal hardware, and is suitable for a variety of IoT and embedded
device solutions. The ACRN hypervisor addresses the gap that currently exists
between datacenter hypervisors, and hard partitioning hypervisors. The ACRN
hypervisor architecture partitions the system into different functional
domains, with carefully selected guest OS sharing optimizations for IoT and
embedded devices.

You can find out more about Project ACRN on the `Project ACRN documentation`_
website.
