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.
