drivers/dai/intel/ssp: Skip setting config when playback/capture is active

Browse source 
The reference count, dp->sref, is never incremented for the SSP DAI as
we use the runtime PM API's to probe/remove the DAI during
resume/suspend. Therefore, use the DAI state to check if the DAI is
active in any direction before proceesing to set the config. This fixes
the IO errors seen during simultaenous playback and capture on the same
SSP.
