ASoC: cs35l56: sdw_write_no_pm() should be performed under a pm_runtime request

SoundWire bus accesses must be performed under the guard of a pm_runtime
request, in this case the write was being performed just after the
request had been put() and so the bus could not be guaranteed to be
available.
