soundwire: qcom: deprecate qcom,din/out-ports

Number of input and output ports can be dynamically read from the
controller registers, getting this value from Device Tree is redundant
and potentially lead to bugs.

Remove the code parsing this property along with marking this as
deprecated in device tree bindings.
