s390x: pv: Fence additional unavailable SCLP facilities for PV guests
There's no VSIE support for a protected guest, so let's better not
advertise it and its support facilities.

target/s390x: Improve cc computation for ADD LOGICAL
The resulting cc is only dependent on the result and the
carry-out. So save those things rather than the inputs.
Carry-out for 64-bit inputs is had via tcg_gen_add2_i64 directly
into cc_src. Carry-out for 32-bit inputs is had via extraction
from a normal 64-bit add (with zero-extended inputs).

target/s390x: Improve cc computation for SUBTRACT LOGICAL
The resulting cc is only dependent on the result and the carry-out.
Carry-out and borrow-out are inverses, so are trivially converted.
With tcg ops, it is easier to compute borrow-out than carry-out, so
save result and borrow-out rather than the inputs.
Borrow-out for 64-bit inputs is had via tcg_gen_sub2_i64 directly
into cc_src. Borrow-out for 32-bit inputs is had via extraction
from a normal 64-bit sub (with zero-extended inputs).

s390x/pci: Fix memory_region_access_valid call
In pcistb_service_handler, a call is made to validate that the memory
region can be accessed. However, the call is made using the entire length
of the pcistb operation, which can be larger than the allowed memory
access size (8). Since we already know that the provided buffer is a
multiple of 8, fix the call to memory_region_access_valid to iterate
over the memory region in the same way as the subsequent call to
memory_region_dispatch_write.

tests/acceptance: Add a test with the Fedora 31 kernel and initrd
This initrd contains a virtio-net and a virtio-gpu kernel module,
so we can check that we can set a MAC address for the network device
and whether we can hot-plug and -unplug a virtio-crypto device.
But the most interesting part is maybe that we can also successfully
write some stuff into the emulated framebuffer of the virtio-gpu
device and make sure that we can read back that data from a screenshot.
