ASoC: SOF: Intel: hda: Create debugfs file to force a clean DSP boot
When IMR boot is supported on a platform it is always going to be used to
boot the DSP unless some catastrophic event happens.
There is no way for a developer to force a clean DSP boot without removing
and re-inserting the modules.
Create a 'skip_imr_boot' debugfs file which can be used to force the
next DSP boot as clean (prune) boot.
