The OBJECT_DECLARE_CPU_TYPE() macro forward-declares each
ArchCPUClass type. These forward declarations are sufficient
for code in hw/ to use the QOM definitions. No need to expose
these structure definitions. Keep each local to their target/
by moving them to the corresponding "cpu.h" header.

Hegerogeneous code needs access to the FOO_CPU_TYPE_NAME()
macro to resolve target CPU types. Move the declaration
(along with the required FOO_CPU_TYPE_SUFFIX) to "cpu-qom.h".
"target/foo/cpu-qom.h" is supposed to be target agnostic
(include-able by any target). Add such mention in the

Enforce the style described by commit 067109a11c ("docs/devel:

The first declaration of a storage or class structure should
always be the parent and leave a visual space between that
declaration and the new code. It is also useful to separate
backing for properties (options driven by the user) and internal
state to make navigation easier.
