ASoC: wcd-dsp-mgr: add argument to the interrupt handler callback

Currently, when manager driver interrupt handler callback is called,
there is no way for the caller to provide any data information along
with the type of interrupt. Change adds argument to the interrupt
handler so that callers can use this to pass agreed data when an
interrupt occurs.
