Series target: Make 'cpu-qom.h' really target agnostic | expand

Commit Message

"target/foo/cpu.h" contains the target specific declarations.

A heterogeneous setup need to access target agnostic declarations
(at least the QOM ones, to instantiate the objects).

Our convention is to add such target agnostic QOM declarations in
the "target/foo/cpu-qom.h" header.

Extract QOM definitions from "cpu.h" to "cpu-qom.h".
