Introduce getHost support for ARM CPU driver. First add
some data about commonly used ARM CPU models, and their
vendors into cpu_map, then added some helper methods as
callbacks to load them. Read and parse vendor_id, part_id
and CPU flags of local CPU from corresponding registers.

Nice, there's a few minor issues that needs fixing, but since I already
did all of them and really checked the code compiles fine after each
patch and tested it can still detect the host CPU, I'll squash the
suggested changes and push the series.
