Subject: [PATCH v2 13/15] arm64: dts: meson: a1: add ao secure node

From: Alexey Romanov <avromanov@...rdevices.ru>

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 Meson A1 SoC:
    soc soc0: Amlogic Meson A1 (A113L) Revision 2c:a (1:a) Detected
