soundwire: intel_auxdevice: enable pm_runtime earlier on startup

As soon as the bus starts, physical peripheral devices may report as
ATTACHED and set their status with pm_runtime_set_active() in their
update_status()/io_init().

This is problematic with the existing code, since the parent
pm_runtime status is changed to "active" after starting the bus. This
creates a time window where the pm_runtime framework can report an
issue, e.g.

"rt711 sdw:0:025d:0711:00: runtime PM trying to activate child device
sdw:0:025d:0711:00 but parent (sdw-master-0) is not active"

This patch enables runtime_pm earlier to make sure the auxiliary
device is pm_runtime active after powering-up, but before starting the
bus.

This problem was exposed by recent changes in the timing of the bus
reset, but was present in this driver since we introduced pm_runtime
support.
