From: Xianwei Zhao <xianwei.zhao at 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 S4 SoC:
soc soc0: Amlogic S4 (S805X2) Revision 37:a (2:1) Detecte
