ASoC: apq8084: Allow sharing of liquid dock plug interrupt



The dock plug detect GPIO is used as an interrupt indicating
when the Liquid device is attached to (or removed from) the
docking station. There may be other peripherals wanting to
register a handler for notification. Hence, allow this
interrupt to be shared by adding the IRQF_SHARED flag.
