Hello all,

This series adds support for early serial printing on Power, as well as
a simple CI smoke test modeled after the riscv one.

The third patch, which implements the serial console, also includes a
set of header additions required to get the build going when including
things like xen/lib.h. When applicable, headers from the old Xen 3.2.3
ppc tree were imported or otherwise empty stub headers were added to be
filled in later.

This will currently only run on QEMU pseries VMs, since the firmware
interface on bare metal differs significantly. Support for bare metal
will be added in a future series.

Thanks,
Shawn
