ASoC: SOF: Intel: hda: Revisit IMR boot sequence
The sequence for IMR boot is essentially the same as normal boot with the
difference that instead of DMA from host the firmware is loaded from IMR.
Re-structure the code to use the existing sequence and also add fallback
handling in case the IMR boot fails.
Introduce a new flag to make the IMR boot support check simpler.
