ASoC: apq8074: register for codec up event

If subsystem restart happens, ADSP loses all the config including AFE
configs. Also codec gets reset and reenumerates on slimbus after ADSP
SSR. So after codec is up ADSP AFE config needs to be done again. But this
AFE config needs to be done after codec reenumerates on slimbus, since
ADSP AFE config expects enumeration of codec on slimbus.
