[PATCH-for-9.0,00/10] hw/xen: Have most of Xen files become target-agnostic

Hi,

After discussing with Alex Bennée I realized most Xen code
should be target-agnostic. David Woodhouse confirmed that
last week, so I had a quick look and here is the result.

More work is required to be able to instanciate Xen HW in
an heterogeneous machine, but this doesn't make sense yet
until we can run multiple accelerators concurrently.

Only build-tested.

Regards,

Phil.
