DynamicTablesPkg: SSDT CPU topology and LPI state generator

Browse Source

In the GIC interrupt model, logical processors are required to
have a Processor Device object in the DSDT and must convey each
processor's GIC information to the OS using the GICC structure.
Additionally, _LPI objects may be needed as they provide a method
to describe Low Power Idle states that defines the local power
states for each node in a hierarchical processor topology.

Therefore, add support to generate the CPU topology and the LPI
state information in an SSDT table.
