Yet another try with XICS and XICS-KVM.

Thanks, applied to ppc-next.


Rebased onto upstream;
Put few "reviewed-by: Andreas";
Added IRQFD enablement patches.

Addressed multiple comments from Alex;
Split out many tiny patches to make them easier to review;
Fixed xics_cpu_setup not to call the parent;
And many, many small changes.

Addressed multiple comments from Andreas;
Added 2 patches for XICS from Ben - I included them into the series as they
are about XICS and they won't rebase automatically if moved before XICS rework

The main change is this adds "xics-common" parent for emulated XICS and 
And many, many small changes, mostly to address Andreas comments.

Migration from XICS to XICS-KVM and vice versa still works.
