[PATCH v2 1/2] arm64: dts: renesas: r8a77970: add GPIO support

[Sergei Shtylyov]

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>.

Signed-off-by: Vladimir Barinov <vladimir.barinov at cogentembedded.com>
Signed-off-by: Sergei Shtylyov <sergei.shtylyov at cogentembedded.com>

---
Changes in version 2:
- made use of the SYSC power domain #define's;
- mentioned the original patch this one was based upon and added Vladimir's
  signoff..
