target-arm: Convert TCG to using (index,value) list for cp migration

Convert the TCG ARM target to using an (index,value) list for migrating
coprocessors. The primary benefit of the (index,value) list is for
passing state between KVM and QEMU, but it works for TCG-to-TCG...

target-arm: Initialize cpreg list from KVM when using KVM

When using KVM, use the kernel's initial state to set up the
cpreg list, and sync to and from the kernel when doing
migration.

target-arm: Reinitialize all KVM VCPU registers on reset

Since the ARM KVM API doesn't include a "reset this VCPU"
ioctl, we have to capture the initial values of every
register it knows about so that we can reset the VCPU
by feeding those values back again....

target-arm: Use tuple list to sync cp regs with KVM

Use the tuple list of cp registers for syncing KVM state to QEMU,
rather than only syncing a very minimal set by hand.

KVM: ARM: Add dummy kvm_arch_init_irq_routing()

The common KVM code insists on calling kvm_arch_init_irq_routing()
as soon as it sees kernel header support for it (regardless of whether
QEMU supports it). Provide a dummy function to satisfy this.

target-arm: Fix incorrect check of kvm_vcpu_ioctl return value

kvm_vcpu_ioctl() returns ETHING on error, not ETHING - correct
an incorrect check in kvm_arch_init_vcpu(). This would not have
had any significant ill-effects -- we would just have propagated...

arm: fix location of some include files

The recent rearrangement of include files had some minor errors:
devices.h is not ARM specific and should not be in arm/
arm.h should be in arm/

Move these two headers to correct this.

hw: move headers to include/

Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches....

target-arm: Use MemoryListener to identify GIC base address for KVM

When using an in-kernel GIC with KVM, we need to tell the kernel where
the GIC's memory mapped registers live. Do this by registering a
MemoryListener which tracks where the board model maps the A15's...

ARM KVM: save and load VFP registers from kernel

Add support for saving and restoring VFP register state from the
kernel. This includes a check that the KVM-created CPU has full
VFP support (as the TCG Cortex-A15 model always does), since for
the moment ARM QEMU doesn't have any way to tweak optional features...
