arm64: topology: Implement basic CPU topology support
Add basic CPU topology support to arm64, based on the existing pre-v8
code and some work done by Mark Hambleton. This patch does not
implement any topology discovery support since that should be based on
information from firmware, it merely implements the scaffolding for
integration of topology support in the architecture.
The goal is to separate the architecture hookup for providing topology
information from the DT parsing in order to ease review and avoid
blocking the architecture code (which will be built on by other work)
with the DT code review by providing something something simple
and basic.
A following patch will implement support for parsing the DT topology
bindings for ARM, similar patches will be needed for ACPI.
