[PATCH 06/16] dt-bindings: arm: renesas, prr: Add new compatible string for RZ/G{L, LC, UL}

RZ/G2{L,LC,UL} SoC's have LSI_DEVID register to retrieve SoC product and
revision information.

RZ/G{L,LC,UL} SoC's have 28-bit product-id compared to other R-Car and
RZ/G2{E,H,M,N} SoC's hence a new compatible string "renesas,devid" is
added.
