[PATCH v2 0/3] soundwire: bus: re-enable CLOCK_STOP_MODE1 support

[Bard Liao]

Add CLOCK_STOP_MODE1 back to allow the peripheral to utilize it when
the clock is stopped.
This mode is designed for power-sensitive devices as it enables a deeper
power-saving state, although it does not retain the peripheral's state
during the clock stop.

v2:
 - check slave->probed before looking at the driver to avoid NULL pointer
   dereference.
 - add wake_enable parameter to stop_bus ops to stop the clock but keep the
   bus unwakeable during system suspend.

  soundwire: bus: add CLOCK_STOP_MODE1 support back
  soundwire: Intel: add wake_enable parameter to stop_bus ops
  soundwire: Intel: stop sdw clock in system suspend
