remoteproc: imx_dsp_rproc: Use start/stop/detect_mode ops from imx_rproc_dcfg

Allow each platform to provide its own implementation of start/stop/
detect_mode operations, and prepare to eliminate the need for multiple
switch-case statements.

Improve code readability and maintainability by encapsulating
platform-specific behavior.

No functional changes.
