arm64: dts: amlogic: a4: add ao secure node

Add node for board info registers, which allows getting SoC family and board revision. For example, with MESON_GX_SOCINFO config enabled we can get the following information for board with Amlogic A4 SoC: soc soc0: Amlogic A4 (A113L2) Revision 40:b (1:1) Detected.
