Subject: [PATCH AUTOSEL 5.18 10/41] ASoC: SOF: Intel: hda-loader: Make sure that the fw load sequence is followed

From: Peter Ujfalusi <peter.ujfalusi@...ux.intel.com>

[ Upstream commit c31691e0d126ec5d60d2b6b03f699c11b613b219 ]

The hda_dsp_enable_core() is powering up _and_ unstall the core in one
call while the first step of the firmware loading  must not unstall the
core.
The core can be unstalled only after the set cpb_cfp and the configuration
of the IPC register for the ROM_CONTROL message.
