Subject: [PATCH] ALSA: dummy: More constifications
Git-commit: d64e7f7c9e70c587ce9fcc2eacd0cd7c29bcf91c
Patch-mainline: v5.6-rc1
References: jsc#SLE-16518

Apply const prefix to every possible place: mostly for declaring the
dummy hardware models.

Just for minor optimization and no functional changes.
