ARM: dts: zynq: drop address cells from GIC node

This is likely a copy-and-paste error from the
ARM GIC documentation, that has already been fixed.

address-cells should have been set to 0, as with the size
cells. As having those properties set to 0 is the
same thing as not specifying them, drop them completely.

ARM: zynq: dt: Add a fixed regulator for CPU voltage

To silence the warning
	cpufreq_cpu0: failed to get cpu0 regulator: -19
from the cpufreq driver regarding a missing regulator,
add a fixed regulator to the DT.
Zynq does not support voltage scaling and the CPU rail should always be
supplied with 1 V, hence it is added in the SOC-level dtsi.
