xen/arm: Small fixes after GICv2 changes by commit ee65c87

The commit ee65c87 moves the GICv2 code in a separate file. Even though this
patch is only deals with code movement, a comment was modify for no reason.

Also rename gicv_v2_init into gicv2v_setup which is what the function does
and less confusing with the other function called gicv2_init.
