kvm tools: arm: emit the MPIDR in DT instead of cpu_id

kvmtools uses the virtual CPU number to emit the DT CPU nodes.
While this is correct for a flat topology, it fails on anything
else, as the guest expects to find the MPIDR there.

The fix is to ask the kernel for each vcpu MPIDR, and emit this
instead.

kvm tools: arm: add support for PSCI firmware in place of spin-tables

ARM has recently published a document describing a firmware interface
for CPU power management, which can be used for booting secondary cores
on an SMP platform, amongst other things. As part of the mach-virt
upstreaming for the kernel (that is, the virtual platform targetted by
kvmtool), it was suggested that we use this interface instead of the
current spin-table based approach.

This patch implements PSCI support in kvmtool for ARM, removing a fair
amount of code in the process.

kvm tools: add support for ARMv7 processors

This patch adds initial support for ARMv7 processors (more specifically,
Cortex-A15) to kvmtool.

Everything is driven by FDT, including dynamic generation of virtio nodes
for MMIO devices (PCI is not used due to lack of a suitable host-bridge).

The virtual timers and virtual interrupt controller (VGIC) are provided
by the kernel and require very little in terms of userspace code.
