ASoC: SDCA: Add NO_DIRECT_COMPLETE flag to class driver

Browse Source 
The SDCA class driver currently expects the device will be fully powered
down on system suspend but not on runtime suspend. This is typically
required as when audio is not active (ie. runtime suspend) jack detect
is expected to still function, but when the whole system is hibernated
there is no need to recognise audio jack events. This means the class
driver needs to always be informed of a system suspend, so the direct
complete optimisation (where PM will skip calling system suspend if the
device is runtime suspended) is not appropriate for the SDCA class
driver.

Add the NO_DIRECT_COMPLETE flag to prevent this optimisation from
running against this driver.
