soundwire: bus: Make IRQ handling conditionally built
SoundWire has provisions for a simple callback for the IRQ handling so
has no hard dependency on IRQ_DOMAIN, but the recent addition of IRQ
handling was causing builds without IRQ_DOMAIN to fail. Resolve this by
moving the IRQ handling into its own file and only add it to the build
when IRQ_DOMAIN is included in the kernel.
Fixes: 12a95123bfe1 ("soundwire: bus: Allow SoundWire peripherals to register IRQ handlers")
