ASoC: wcd9310: Ensure system is awake while accessing CODEC registers

If Tabla ISRs are called when system is in suspended state,
there are chances that Tabla and underlying bus are not awake.
Fix ISRs to wait until devices are awaken and prevent system from
suspending while accessing bus is completed.
