vgic.c is currently a mixture of generic vGIC emulation code and
functions specific to emulating a GICv2. To ease the addition of
GICv3 later, we create new header file vgic.h, which holds constants
and prototypes of commonly used functions.
Rename some identifiers to avoid name space clutter.
I removed the long-standing comment about using the kvm_io_bus API
to tackle the GIC register ranges, as it wouldn't be a win for us
anymore.

- vgic_init()
- vgic_update_state()
- vgic_kick_vcpus()
- vgic_get_vmcr()
- vgic_set_vmcr()
- struct mmio_range {} (renamed to struct kvm_mmio_range)
* removed static keyword and exported prototype in vgic.h:
- vgic_bitmap_get_reg()
- vgic_bitmap_set_irq_val()
- vgic_bitmap_get_shared_map()
- vgic_bytemap_get_reg()
