andrew cd458c627d Add basic support for ACPI. It splits out the nexus driver to two new
drivers, one for fdt, one for acpi. It then uses this to decide if it will
use fdt or acpi.

The GICv2 (interrupt controller) and Generic Timer drivers have been
updated to handle both cases.

As this is early code we still need FDT to find the kernel console, and
some parts are still missing, including PCI support.
