On Qualcomm platforms, like QCS6490-RB3Gen2 and QCM6490-IDP, 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).
