tools: config-create: Do not enter infinite over disabled PCI devices
If a PCI device is disabled, e.g. a secondary GPU, we may not see its
config space anymore while it is still listed. With config all 0xff, we
will then enter an infinite loop while trying to make sense of the
capability list. Prevent this, issuing a warning that we will skip this
device.

x86: Officially support VT-d Caching Mode != 0
We already flush all domain-related caches after reconfigurations,
irrespective of the address ranges changed and how they were changed
(made valid or invalid). So the feature check during unit setup is
actually superfluous - remove it.

driver: Destroy non-root cells before disabling the hypervisor
The hypervisor's disable function will lose support for destroying
non-root cells along with the shutdown. Prepare for this by performing
an explicit non-root cell destruction prior to calling the shutdown
command.

Log Message:
-----------
core: Deny shutdown with still existing non-root cells
Simplify the shutdown logic by requiring the root cell driver to
explicitly destroy all non-root cells first. In particular, it helps to
resolve the tricky handover of non-root cell CPUs in unplugged state to
Linux.
At this chance, properly document potential races around the shutdown
and other management hypercalls. They are non-obvious but harmless for
the integrity of any non-root cell.

x86, arm: Remove unused arch_shutdown_cpu
Now that we no longer need to shut down non-root CPUs directly, we can
get rid of this arch function. On x86, it also allows the removal of
per_cpu::shutdown_cpu and related handling. On ARM, we can drop the
PSCI_CPU_OFF call from arch_reset_self and the irqchip_cell_exit for
non-root cells from arch_shutdown.

Rework ARM to fix races and cache corruptions
PSCI was completely broken, cache flushes corrupted the hypervisor
state, and we need to reset __boot_cpu_mode after onlinening CPUs under
Jailhouse. This requires break-ups, and vexpress is broken.
