arm64: dts: qcom: hamoa-iot-evk: Fix 4-speaker playback support

On the HAMOA-IOT-EVK board only 2 out of 4 speakers were functional.
Unlike the CRD, which shares a single GPIO reset line for WSA1/2,
this board provides a dedicated GPIO reset for each WSA, resulting
in 4 separate reset lines.

Update the device tree accordingly so that all 4 speakers can
playback audio as expected.
