soundwire: cadence_master: set data_per_frame as frame capability
data_per_frame will be used for preparing the TX buffer and we may add
some fake frames to ensure the data in the buffer will be flushed.
So that it should indicate the frame capability even if the required
data bytes are less than the frame capability.
