[PATCH v8 02/16] arm: use new phandle allocation functions

[andre.przywara@arm.com (Andre Przywara)]

To refer to the GIC FDT node, we used to pass the GIC phandle to most
of the functions dealing with FDT nodes.
Since we now have a global phandle reference, use that to refer to the
GIC handle in various places and get rid of the now unneeded parameter
passing.
