ASoC: SDCA: Rely less on the ASoC component in IRQ handling

In the future some IRQs (mostly the UMPs used during File
DownLoad) will need to run after the device has enumerated on the
bus but before the soundcard is actually constructed. As such
refactor more of the IRQ handling to use raw device and regmap
pointers, rather than accessing things through the component.
