feat(tc): change GIC DT property 'interrupt-cells' to 4

Change the GIC's DT property 'interrupt-cells' to 4, so the 4th cell is
a phandle to a node describing a set of CPUs this interrupt is affine
to.

If an interrupt is a PPI, and the node pointed in the 4th cell must be a
subnode of the "ppi-partitions" in the GIC node. For interrupt types
other than PPI, this cell must be zero. This is a preparison for
sequential changes for interrupt partitions, as the first step, it sets
all zeros for the interrupt affinity.
