arm64: dts: qcom: x1e80100-crd: switch WSA8845 speakers to shared reset-gpio
Each pair of WSA8845 speakers share the powerdown SD_N GPIO, thus this
GPIO is specified twice in each WSA8845 device node. Such DTS was added
hoping non-exclusive GPIO usage would be accepted, but it turned out
otherwise: it is not supported by the Linux kernel.
Linux kernel however supports sharing reset GPIOs, when used bia the
reset controller framework as implemented in commit 26c8a435fce6 ("ASoC:
dt-bindings: qcom,wsa8840: Add reset-gpios for shared line") and
commit c721f189e89c ("reset: Instantiate reset GPIO controller for
shared reset-gpios").
Convert the property with shutdown GPIO to "reset-gpios" to use
mentioned Linux kernel feature. This allows to bring all four speakers
out of reset.
