[PATCH v6 5/6] ASoC: dt-bindings: qcom,wsa8840: Add reset-gpios for shared line

[Krzysztof Kozlowski]

On newer Qualcomm platforms, like X1E80100-CRD, the WSA884x speakers
share SD_N GPIOs between two speakers, thus a coordinated assertion is
needed.  Linux supports handling shared GPIO lines through "reset-gpios"
property, thus allow specifying either powerdown or reset GPIOs (these
are the same).

If previous patches are fine, then this commit is independent and could
be taken via ASoC.
