While at it, I've also fixed some typos that were present in the original txt binding, as it was suggesting that the compatible string would have "mediatek,cirq" as compatible but, in reality, that's supposed to be "mediatek,mtk-cirq" instead. Little rewording on property descriptions also happened for them to be more concise.
