We plan to use vgic_find_mmio_region in vgic-its.c so let's
turn it into a public function.

Also let's take the opportunity to rename the region parameter
into regions to emphasize this latter is an array of regions.

v4 -> v5:
- add Marc's A-b

v3 -> v4:
- rename region parameter into regions
- add Andre's R-b

nit: we don't usually comment the functions in the prototype in the
header files but keep comments with the function implementation.

But I don't care deeply about this.
