Subject: [PATCH v4 00/12] remoteproc: imx_dsp_rproc: Refactor to use new
 ops and remove switch-case logic

This patchset aligns imx_dsp_rproc with the cleanup and modernization
previously applied to imx_rproc.c. The goal is to simplify the driver by
transitioning to the new ops-based method, eliminating the legacy
switch-case logic for a cleaner and more maintainable design.

Patches 1–5: General cleanup, including code simplification and adoption
             of the devres API.
Patches 6–10: Transition to the new ops-based approach, removing the
              switch-case structure.
Patch 11: Remove the obsolete enum imx_rproc_method.
Patch 12: Cleanup goto based logic.
