Most of the QEMU changes for PV are related to the new IPL type with
subcodes 8 - 10 and the execution of the necessary Ultravisor calls to
IPL secure guests. Note that we can only boot into secure mode from
normal mode, i.e. stfle 161 is not active in secure mode.
The other changes related to data gathering for emulation and
disabling addressing checks in secure mode, as well as CPU resets.
V3:
* Use dedicated functions to access SIDA
* Smaller cleanups and segfault fixes
* Error reporting for Ultravisor calls
* Inject of RC of diag308 subcode 10 fails
V2:
* Split out cleanups
* Internal PV state tracking
* Review feedback
