ASoC: Intel: avs: New IRQ handling implementation

The existing code can be both improved and simplified. To make this
change easier to manage, first add new implementation and then remove
deadcode in a separate patch.

Simplification achieved with:
- reduce the amount of resources requested by the driver i.e.: IPC and
  CLDMA request_irq() merged into one
- reduce the number of DSP ops from 2 to 1:
  irq_handler/thread() vs dsp_interrupt()
- drop ambiguity around CLDMA interrupt, let skl.c handle that
  explicitly as it is the only user
