Subject: [PATCH] ASoC: SOF: Intel: hda: use SOF defined init chip in resume
Git-commit: d06973515f95ac74d68fb3e1f1fb4b055531296c
No-fix: 9c6c417d95d83999c16965186f6e755ad8a8b658
Patch-mainline: v5.4-rc1
References: jsc#SLE-16518

Unify resume code by using SOF common function hda_dsp_ctrl_init_chip()
which can handle both HDA and non-HDA cases. Move code to reset
stream-to-link mapping into hda_dsp_ctrl_init_chip().
