As determined by experimentation and asking a hardware person, the FIFO
in the Cadence IP is actually only 8 entries long, not 32. This is fixed
in patch #1.

As a bonus, patches #2 and #3 fix two other things I noticed while
debugging this.

Richard Fitzgerald (3):
  soundwire: cadence: Don't overflow the command FIFOs
  soundwire: cadence: Remove wasted space in response_buf
  soundwire: cadence: Drain the RX FIFO after an IO timeout
