[PATCH 5.10.y-cip 24/28] arm64: dts: renesas: r9a08g045: Use syscon compatible for the system controller

From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>

RZ/G3S PCIe driver needs the system controller syscon to be able to set
its registers. For this, it uses syscon_node_to_regmap(). But, in v6.1
CIP, the syscon_node_to_regmap() returns ERR_PTR(-EINVAL) if the node
for which it is called don't have the syscon compatible.

Add syscon compatible for the system controller.
