Subject: [PATCH v7 4/6] arm64: dts: renesas: r9a09g047: Add #address-cells property in sys node

A couple of registers of the system controller (sys) are shared with the TSU
device. Add #address-cells property to sys node to allow proper parsing a
access to these registers from the TSU driver.

Signed-off-by: John Madieu <john.madieu.xa@...renesas.com>

Changes:
 - v7: new patch: as sys specifier has changed for TSU node, add this patch
 to specify #address-cells.
