From: Arnd Bergmann <arnd@arndb.de>

Without CONFIG_PM, the driver warns about unused functions:

drivers/remoteproc/imx_dsp_rproc.c:1210:12: error: 'imx_dsp_runtime_suspend' defined but not used [-Werror=unused-function]
 1210 | static int imx_dsp_runtime_suspend(struct device *dev)
      |            ^~~~~~~~~~~~~~~~~~~~~~~
drivers/remoteproc/imx_dsp_rproc.c:1178:12: error: 'imx_dsp_runtime_resume' defined but not used [-Werror=unused-function]
 1178 | static int imx_dsp_runtime_resume(struct device *dev)
      |            ^~~~~~~~~~~~~~~~~~~~~~

Change the old SET_SYSTEM_SLEEP_PM_OPS()/SET_RUNTIME_PM_OPS()
helpers to their modern replacements that avoid the warning,
and remove the now unnecessary __maybe_unused annotations
on the other PM helper functions.
