Assuming there is a GIC distributor at address GICD_BASE, this patch
checks its version and call the gic init function. Linux's kconfig header
is used to guess the base address of the distributor.
Ideally, a device tree would be passed to the hypervisor in the root
cell's config, allowing to remove all constant base addresses.
The patch also assumes that most of the GIC has been setup by Linux prior
to the hypervisor installation, and only initialises the vGIC.
