ASoC: SOF: Intel: hda: Use cold/purge boot after firmware crash

Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:

In case of a firmware crash we force the DSP to be powered down and rebooted.
To make sure that the next boot is going to be clean, force the boot process to
skip the IMR booting and re-download the firmware.
