We expose loadparm as a r/w machine property, but if loadparm is set by
the guest via DIAG 308, we don't update the property. Having a
disconnect between the guest view and the QEMU property is not nice in
itself, but things get even worse for SCSI, where under certain
circumstances (see 789b5a401b "s390: Ensure IPL from SCSI works as
expected" for details) we call s390_gen_initial_iplb() on resets
effectively overwriting the guest/user supplied loadparm with the stale
value.

The POP states that for a list directed IPL the IPLB is stored into
memory by the machine loader and its address is stored at offset 0x14
of the lowcore.
ZIPL currently uses the address in offset 0x14 to access the IPLB and
acquire flags about secure boot. If the IPLB address points into
memory which has an unsupported mix of flags set, ZIPL will panic
instead of booting the OS.
As the lowcore can have quite a high entropy for a guest that did drop
out of protected mode (i.e. rebooted) we encountered the ZIPL panic
quite often.

The vtd_find_as_from_bus_num() function was introduced (in commit
dbaabb25f) in a code format that could return an incorrect pointer,
which was later fixed by commit a2e1cd41cc.
We could have avoided this by writing the if() statement differently.
Do it now, in case this function is re-used. The code is easier to
review (harder to miss bugs).

We turn on device IOTLB via VIRTIO_F_IOMMU_PLATFORM unconditionally on
platform without IOMMU support. This can lead unnecessary IOTLB
transactions which will damage the performance.
Fixing this by check whether the device is backed by IOMMU and disable
device IOTLB.

Make hot-plug/hot-unplug on PCIe Root Ports optional to allow libvirt
manage it and restrict unplug for the whole machine. This is going to
prevent user-initiated unplug in guests (Windows mostly).
Hotplug is enabled by default.
Usage:
-device pcie-root-port,hotplug=off,...
If you want to disable hot-unplug on some downstream ports of one
switch, disable hot-unplug on PCIe Root Port connected to the upstream
port as well as on the selected downstream ports.
