Subject: [PATCH v3 1/3] ASoC: dt-bindings: qcom,wsa8830: Add reset-gpios for shared line

On Qualcomm platforms such as QCS6490-RB3Gen2, the WSA883x speaker
amplifiers share the SD_N GPIO line between two speakers, thus
requires coordinated control when asserting the GPIO. Linux supports
shared GPIO handling via the "reset-gpios" property, which can be
used to specify either the powerdown or reset GPIOs.
