[PATCH 47/53] arm64: dts: renesas: r8a774a1: Add CPU topology on r8a774a1 SoC

[Simon Horman]

From: Biju Das <biju....@bp.renesas.com>

This patch adds the "cpu-map" into r8a774a1 composed of multi-cluster. This
definition is used to parse the cpu topology.

Based on work by Gaku Inami <gaku.inami...@bp.renesas.com> for r8a7796 SoC.
