dt-bindings: gpu: mali-bifrost: Add compatible for RZ/G3E SoC

Add a compatible string for the Renesas RZ/G3E SoC variants that
include a Mali-G52 GPU. These variants share the same restrictions on
interrupts, clocks, and power domains as the RZ/G2L SoC, so extend
the existing schema validation accordingly.
