dt-bindings: soundwire: qcom: add 16-bit sample interval 



The port sample interval was always 16-bit, split into low and high
bytes.  This split was unnecessary, although harmless for older devices
because all of them used only lower byte (so values < 0xff).  With
support for Soundwire controller on Qualcomm SM8550 and its devices,
both bytes will be used, thus add a new 'qcom,ports-sinterval' property
to allow 16-bit sample intervals.
