ASoC: amd: ps: add support for SoundWire DMA interrupts

Move to request_threaded_irq and use thread for handling
SoundWire DMA interrupts.
Whenever audio data equal to the SoundWire FIFO watermark level
are produced/consumed, interrupt is generated.
Acknowledge the interrupt and wake up the irq thread.
