Victor Sun bfecf30f32 HV: do not offline pcpu when lapic pt disabled
In current code, wait_pcpus_offline() and make_pcpu_offline() are called by
both shutdown_vm() and reset_vm(), but this is not needed when lapic_pt is
not enabled for the vcpus of the VM.

The patch merged offline pcpus part code into a common
offline_lapic_pt_enabled_pcpus() api for shutdown_vm() and reset_vm() use and
called only when lapic_pt is enabled.

Tracked-On: #4325

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.
