[PATCH v3 4/6] arm64: dts: amlogic: c3: add ao secure node

[Xianwei Zhao via B4 Relay <devnull+xianwei.zhao.amlogic.com@kernel.org>]

From: Xianwei Zhao <xianwei.zhao@amlogic.com>

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
