Subject: [PATCH v2 12/15] arm64: dts: renesas: Add #renesas,sysc-signal-cells to system controller node

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

The system controller on RZ/G3S can provide control access to its signals.
To enable this, add the #renesas,sysc-signal-cells DT property. Consumers
can use the renesas,sysc-signal DT property to reference the specific SYSC
signal that needs to be controlled.
