arm64: dts: mediatek: mt7622: drop "reset-names" from thermal block

Binding doesn't specify "reset-names" property and Linux driver also
doesn't use it.

Fix following validation error:
arch/arm64/boot/dts/mediatek/mt7622-rfb1.dtb: thermal@1100b000: Unevaluated properties are not allowed ('reset-names' was unexpected)
        from schema $id: http://devicetree.org/schemas/thermal/mediatek,thermal.yaml#
