[PATCH 0/2] soundwire: remove unnecessary scale_index programming

[Bard Liao]

We can skip the unattached Peripherals when programing the scale_index
register. Because the frequency will be set when the Peripheral is
attached. And It is not necessary to program the scale_index if the new
index is the same as the current one.

  soundwire: don't program SDW_SCP_BUSCLOCK_SCALE on a unattached
    Peripheral
  soundwire: record Peripheral scale_index
