[PATCH 05/10] ASoC: Intel: avs: Abstract IRQ handling

[Cezary Rojewski <cezary.rojewski@intel.com>]

Servicing IPCs on CNL platforms and onward differs from the existing
one. To make room for these, relocate SKL-based platforms specific code
into the skl.c file leaving only the genering irq_handler in the common
code.
