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.
