02c4c29823 qemu: capabilities: Retire QEMU_CAPS_VIRTIO_PCI_IOMMU_PLATFORM
The capability reflects whether QEMU is capable of -device
virtio-*,iommu_platform=. Since the property was introduced in
QEMU commit v2.9.0-rc0~162^2~37 we can safely assume the property
is always present as the minimal version required is 2.11.0.

da20199762 qemu: capabilities: Assume QEMU_CAPS_AES_KEY_WRAP and QEMU_CAPS_DEA_KEY_WRAP for s390 only
qemu introduced these options in 2eb1cd0768 ("s390x: CPACF: Handle key
wrap machine options") released in qemu-v2.3.0 but was exposed in
query-command-line-options only in 5bcfa0c543 ("util/qemu-config: fix
missing machine command line options").

The problem is that they are exposed even for architectures which don't
actually in fact support those.

Make the two capabilities a bit more useful by assuming them only on
s390 and thus removing them from other arches.

7b1ed1cd73 qemu: stop passing -enable-fips to QEMU >= 5.2.0
Use of the -enable-fips option is being deprecated in QEMU >= 5.2.0. If
FIPS compliance is required, QEMU must be built with libcrypt which will
unconditionally enforce it.

Thus there is no need for libvirt to pass -enable-fips to modern QEMU.
Unfortunately there was never any way to probe for -enable-fips in the
first instance, it was enabled by libvirt based on version number
originally, and then later unconditionally enabled when libvirt dropped
support for older QEMU. Similarly we now use a version number check to
decide when to stop passing -enable-fips.

Note that the qemu-5.2 capabilities are currently from the pre-release
version and will be updated once qemu-5.2 is released.
