[PATCH v2 1/3] dt-bindings: mfd: mediatek: mt6397: Add #sound-dai-cells property

[Julien Massot <julien.massot@collabora.com>]

The 'mt6359.dtsi' file already uses the '#sound-dai-cells' property.
Add the corresponding property to the binding to fix the following
dtb-check error:

mediatek/mt8395-radxa-nio-12l.dtb: pmic: '#sound-dai-cells', 'mt6359rtc' do not match any of the regexes: 'pinctrl-[0-9]+'
from schema $id: http://devicetree.org/schemas/mfd/mediatek,mt6397.yaml#

Fixes: 9bc8353be720 ("arm64: dts: mt6359: Add #sound-dai-cells property")
