[PATCH v2 03/10] dt-bindings: gpu: mali-bifrost: Allow up to 5 power domains for MT8192

[AngeloGioacchino Del Regno <angelogioacchino.delregno@xxxxxxxxxxxxx>]

MediaTek MT8192 (and similar) needs five power domains for the
Mali GPU and no sram-supply: change the binding to allow so.

Fixes: 5d82e74a97c2 ("dt-bindings: Add compatible for Mali Valhall (JM)")
