[PATCH] dt-bindings: arm: renesas: Add HopeRun RZ/G2N boards

[Biju Das <biju.das@xxxxxxxxxxxxxx>]

This patch adds board HiHope RZ/G2N (the main board, powered by
the R8A774B1) and board HiHope RZ/G2 EX (the expansion board
that sits on top of the HiHope RZ/G2N). Both boards are made
by Jiangsu HopeRun Software Co., Ltd. (a.k.a. HopeRun).
