Add an MMIO handling framework to the VGIC emulation: Each register is described by its offset, size (or number of bits per IRQ, if applicable) and the read/write handler functions. We provide initialization macros to describe each GIC register later easily. Separate dispatch functions for read and write accesses are connected to the kvm_io_bus framework and binary-search for the responsible register handler based on the offset address within the region. We convert the incoming data (referenced by a pointer) to the host's endianess and use pass-by-value to hand the data over to the actual handler functions. The register handler prototype and the endianess conversion are courtesy of Christoffer Dall.
