ASoC: amd: ps: fix for irq handler return status

If any Soundwire manager interrupt is reported, and wake interrupt
is not reported, in this scenario irq_flag will be set to zero,
which results in interrupt handler return status as IRQ_NONE.

Add new irq flag 'wake_irq_flag' check for SoundWire wake interrupt
handling to fix incorrect irq handling return status.
