Changing input state in iec capture control is not safe,
as the pin state may be changed concurrently by ASoC
framework.
Remove pin state handling in iec capture control.
Note: This introduces a restriction on capture control,
when pin sleep state is defined in device tree. In this case
channel status can be captured only when an audio stream
capture is active.
