remoteproc: imx_rproc: Clean up after ops introduction

With the switch-case in imx_rproc_{start,stop}{} removed, simplify
the code logic by removing 'goto'. The last switch-case in
imx_rproc_detect_mode() are no longer needed and can be removed.

This cleanup improves code readability and aligns with the new ops-based
design.

No functional changes.
