Subject: [PATCH 4/4] arm64: dts: qcom: x1e80100-crd: add WSA8845 speakers

Add nodes for four WSA8845 speakers.  Unlike previous boards like
SM8550-QRD, this board has four speakers spread over two Soundwire buses
instead of two speakers on one bus.  Each pair of speakers shares the
reset GPIO thus pinctrl property is only in one of them.
