target-arm: Add GIC phandle to VirtBoardInfo 

Instead of passing the GIC phandle around between functions, add it to
the VirtBoardInfo just like we do for the clock_phandle.  We are about
to add the v2m phandle as well, and it's easier not having to pass
around a bunch of phandles, return multiple values from functions, etc.
