tools: config-create: Adjust defaults to qemu-x86 setup
This allows to reuse the existing inmate configs more easily. 6M of
hypervisor memory is much less than before but should only be a problem
on very large or very old (no VT-d hugepages) systems, so it's
practically fine.

configs: Add support for MACCHIATObin board
Add configs for the Marvell Armada 8040-based MACCHIATObin board.
As we set the pci_domain to 1 and the upstream kernel does not
initialize linux,pci-domain, we need a patch to the DTB for the time
being.
MSI support should eventually be possible as well, but we still with
INTx for the virtual shmem devices for now.

Due to the way how CPU 0 is offlined on x86, we cannot "steal" it from
the root cell and give it to a different owner. Catch any configuration
that tries to do so and reject this attempt.

x86: Clarify and improve rejection of NMI IPIs
While technically doable, re-injecting NMIs from the hypervisor into a
guest is far from being simple. On Intel, we need to take care of
various cases where injection could have failed. On AMD, it even takes
single-stepping over the IRET instruction in order to get to the end of
an NMI-blocking window.
So, remove the to-do note, replacing it with a hint that NMI IPIs will
likely remain unsupported for a longer time. At this chance augment the
printed message with the target CPU of the IPI. This may help to
correlate the effect of a missing NMI or the reason for the injection
(stalled CPU).

driver: Add per-cpu statistics
The hypervisor already provides us the counter CPU-specific, we just
need to expose them separated, in addition to the existing accumulated
representation. This helps to identify hypervisor interferences in
multicore cells that use core-specific workload.
The CPU-specific statistics are created for all CPUs during root cell
setup as separate kobjects. When a non-root cell is create the kobjects
associated with those CPUs that this cell is assigned are simply moved
from the root cell to the new one. On non-root cell destruction, the
kobjects are moved back. They are truly destroyed on root cell
tear-down.

arm-common: account for SMC exits
Statistics on ARM currently has some imbalances: the total number of
exits doesn't equal the sum of the fine granular exit counters: we
aren't accounting for SMCCC exits.
Fix this by adding a new statistic counter for SMCCC.
PSCI exits are already accounted inside psci_dispatch(), move SMCCC
accounting to the dispatcher routine handle_smc().
