Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.7-20160701' into staging

ppc patch queue 2016-07-01

Here's the current ppc patch queue. This is a fairly large batch,
containing:
* A number of further preliminary patches towards full hypervisor
mode emulation
* Some further fixes / cleanups for the recently merged device_add
based CPU hotplug
* Preliminary patches towards supporting a native (rather than
paravirtualized) XICS device. This will be needed to emulate a
physical Power machine, including hypervisor capabilities
* Assorted bug fixes

ppc/xics: Replace "icp" with "xics" in most places

The "ICP" is a different object than the "XICS". For historical reasons,
we have a number of places where we name a variable "icp" while it contains
a XICSState pointer. There *is* an ICPState structure too so this makes
the code really confusing.

This is a mechanical replacement of all those instances to use the name
"xics" instead. There should be no functional change.

ppc/xics: Implement H_IPOLL using an accessor

None of the other presenter functions directly mucks with the
internal state, so don't do it there either.
