ASoC: SOF: Intel: hda: add per-chip enable_sdw_irq() callback
Different generations of Intel hardware rely on different programming
sequences to enable SoundWire IP. In existing hardware, the SoundWire
interrupt is enabled with a register field in the DSP register
space. With HDaudio multi-link extensions registers, the SoundWire
interrupt will be enabled with a generic interrupt enable field in
LCTL, without any dependency on the DSP being enabled.
Add a per-chip callback following the example of the check_sdw_irq()
model already upstream.
Note that the callback is not populated yet for MeteorLake (MTL) since
the interrupts are already enabled in the init. A follow-up patch will
move the functionality to this callback after a couple of cleanups.
