[PATCH 21/69] arm64: dts: renesas: r8a77970: add GPIO support

[Simon Horman]

From: Sergei Shtylyov <sergei.shtylyov at cogentembedded.com>

Describe all 6 GPIO controllers in the R8A77970 device tree.

Based on the original (and large) patch by Daisuke Matsushita
<daisuke.matsushita.ns at hitachi.com>.
