From: Martyn Welch <martyn.welch@collabora.com>

In the next commit we will be adding the M4F driver which shares a lot of
commonality with the DSP driver. Split this shared functionality out so
that it can be used by both drivers.

Changes since v2:
 - New patch (reordered refactored from v2)

Changes since v3:
 - Removed "ipc_only" element from k3_rproc structure
 - Refactored to bring 3 more common functions

Changes since v4:
 - None

Changes since v5:
 - Rearranged the functions order to match with the functions in
   ti_k3_dsp_remoteproc.c to ease review.

Generate your patch correctly with -M/-B/-C so the move will be detected.
