Merge series "ASoC: SOF: DSP core management fixes for 5.10" from Kai Vehmanen <kai.vehmanen@linux.intel.com>:

This series contains some improvements to how DSP core management
is done in SOF, and adds a distinction between cores managed by
the host versus cores managed by the DSP.

Pierre-Louis Bossart (1):
  ASoC: SOF: Intel: hda-loader: s/master/primary

Ranjani Sridharan (3):
  ASoC: SOF: rename cores_mask to host_managed_cores_mask
  ASoC: SOF: Intel: hda: modify core_power_up/down op
  ASoC: SOF: Intel: remove the  HDA_DSP_CORE_MASK() macro
