ArmVirtPkg: kvmtool platform memory map

Kvmtool is a virtual machine manager that enables
hosting KVM guests. Kvmtool allows to vary the
hardware configuration of the virtual platform
it provides to the guest partition. It provides
the current hardware configuration to the firmware
by handing off a device tree containing the hardware
information.

This library parses the kvmtool provided device
tree and populates the system memory map for the
kvmtool virtual platform.
