ASoC: rt715-sdca: enable pm_runtime in probe, keep status as 'suspended'
This patch suggests enabling pm_runtime during the probe, but marking the
device as 'active' only after it is enumerated. That will force a
dependency between the card and the codec, pm_runtime_get_sync() will
have to wait for the codec device to resume and hence implicitly wait
for the enumeration/initialization to be completed. In the nominal
case where the codec device is already active the get_sync() would
only perform a ref-count increase.
The changes are directly inspired by RT711 and RT711-sdca changes.
