ASoC: rsnd: add .irq callback
Current rsnd driver has .init/.start/.stop/.quit callbacks,
and it needs many IPs (SRC/CTU/MUX/DVC/CMD/SSIU/SSI).
Because of these relationship, it might get unnecessary
error IRQ when start/stop.
This patch adds new .irq callback and control IRQ enable/disable
timing to avoid it.
