arm64: dts: qcom: sc8280xp: correct Soundwire wakeup interrupt name

The bindings expect second Soundwire interrupt to be "wakeup" (Linux
driver takes by index):

  sc8280xp-crd.dtb: soundwire-controller@3330000: interrupt-names:1: 'wakeup' was expected

Fixes: c18773d1 ("arm64: dts: qcom: sc8280xp: add SoundWire and LPASS")
