[PATCH v3 1/3] dt-bindings: gpu: mali-bifrost: Document RZ/G2L support

[Biju Das]

The Renesas RZ/G2{L, LC} SoC (a.k.a R9A07G044) has a Bifrost Mali-G31 GPU,
add a compatible string for it.

v2->v3:
 * Moved optional clock-names and reset-names to SoC-specific conditional schemas.
 * minimum number of reset for the generic GPU is set to 1.
 * Documented number of clocks, resets, interrupts and interrupt-names in RZ/G2L
   SoC-specific conditional schemas.
v1->v2:
 * Updated minItems for resets as 2
 * Documented optional property reset-names
 * Documented reset-names as required property for RZ/G2L SoC.
