soundwire: bus: iterate DT compatibles for class-ID match

sdw_of_find_slaves() reads only the first "compatible" string on a
SoundWire slave DT node and rejects the node if that string does not
parse as sdwVMMMPPPPXX.  This prevents the standard DT convention of
placing a vendor-variant compatible ahead of the SoundWire class-ID
compatible:

    compatible = "vendor,partname", "sdwVMMMPPPPXX";

Iterate every string in the compatible property and accept the first
one that parses as a SoundWire class ID.  The vendor-variant string
remains visible to driver probe callbacks via device_is_compatible()
for mode/variant disambiguation.
