Subject: [PATCH 1/2] dt-bindings: soc: renesas: renesas,rzg2l-sysc: Document RZ/Five SoC

Document RZ/Five (R9A07G043) SYSC bindings. SYSC block found on the
RZ/Five SoC is almost identical to one found on the RZ/G2L (and alike)
SoC's. To differentiate RZ/G2UL from RZ/Five, "-rzfive" is included in
the compatible string for the RZ/Five SoC as there are no interrupts
from the SYSC block to the core.
