[ 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.
