powerpc/xics: Rewrite XICS driver
This is a significant rework of the XICS driver, too significant to
conveniently break it up into a series of smaller patches to be honest.
The driver is moved to a more generic location to allow new platforms
to use it, and is broken up into separate ICP and ICS "backends". For
now we have the native and "hypervisor" ICP backends and one common
RTAS ICS backend.
The driver supports one ICP backend instanciation, and many ICS ones,
in order to accomodate future platforms with multiple possibly different
interrupt "sources" mechanisms.
