GICR for multiple CPU can be described with start address and stride,
or with multiple address. Current multiple address and stride are
both used. Fix it.

Add clock controller nodes, including one top controller
two low speed controllers and one audio controller.

Please drop the leading zeros from unit-address in node name.

the mm/vmalloc.c changes.
