arm64: dts: amlogic: t7: 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 T7 SoC:
soc soc0: Amlogic T7 (A311D2) Revision 36:c (1:1) Detected.
