arm64: dts: amlogic: c3: 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 C3 SoC:
soc soc0: Amlogic C3 (C308L) Revision 3d:a (1:1) Detected
