To avoid complication in code that otherwise would not need to
care about whether EL1 is AArch32 or AArch64, we should store
the interrupt mask bits (CPSR.AIF in AArch32 and PSTATE.DAIF
in AArch64) in one place consistently regardless of EL1's mode.
Since AArch64 has an extra enable bit (D for debug exceptions)
which isn't visible in AArch32, this means we need to keep
the enables in env->pstate. (This is also consistent with the
general approach we're taking that we handle 32 bit CPUs as
being like AArch64/ARMv8 CPUs but which only run in 32 bit mode.)

Implement the AArch64 TTBR* registers. For v7 these were already 64 bits
to handle LPAE, but implemented as two separate uint32_t fields.
Combine them into a single uint64_t which can be used for all purposes.
Since this requires touching every use, take the opportunity to rename
the field to the architectural name.

Save and restore the ARM KVM VGIC state from the kernel. We rely on
QEMU to marshal the GICState data structure and therefore simply
synchronize the kernel state with the QEMU emulated state in both
directions.
We take some care on the restore path to check the VGIC has been
configured with enough IRQs and CPU interfaces that we can properly
restore the state, and for separate set/clear registers we first fully
clear the registers and then set the required bits.

Support creating the ARM vgic device through the device control API and
setting the base address for the distributor and cpu interfaces in KVM
VMs using this API.
Because the older KVM_CREATE_IRQCHIP interface needs the irq chip to be
created prior to creating the VCPUs, we first test if we can use the
device control API in kvm_arch_irqchip_create (using the test flag from
the device control API). If we cannot, it means we have to fall back to
KVM_CREATE_IRQCHIP and use the older ioctl at this point in time. If
however, we can use the device control API, we don't do anything and
wait until the arm_gic_kvm driver initializes and let that use the
device control API.

The ethernet device in the musicpal only has two tx queues,

array is only 2 entries long this allowed a guest to overrun
this buffer. Remove the nonexistent registers.

The virtio_net offload APIs are used on the NIC's peer (i.e. the tap
device). The API was defined to implicitly use nc->peer, saving the
caller the trouble.
This wasn't ideal because:
1. There are callers who have the peer but not the NIC. Currently they
are forced to bypass the API and access peer->info->... directly.
2. The rest of the net.h API uses nc, not nc->peer, so it is
inconsistent.
This patch pushes nc->peer back up to callers.

* read functions return the value rather than taking a pointer
