armvirt: new target
An ARM Cortex-A15 machine provided by QEMU.
Kernel drivers enabled:
- pl011, uart
- pl031, rtc
- pl061, gpio
- pci-host-generic
- virtio_{mmio,pci,net,blk,scsi,9p,console,balloon}
- smp with NR_CPUS=4
- cpu-hotplug
- ext4
- neon, vfp extensions support (otherwise userland will fail with
illegal instruction signal (code 0x00000004))
- DEBUG_BUGVERBOSE for debug purposes
