remoteproc: imx_dsp_rproc: mark PM functions as __maybe_unused

Browse Source 
When CONFIG_PM_SLEEP is disabled, we get a harmless warning:

drivers/remoteproc/imx_dsp_rproc.c:1145:12: error: 'imx_dsp_resume' defined but not used [-Werror=unused-function]
 1145 | static int imx_dsp_resume(struct device *dev)
      |            ^~~~~~~~~~~~~~
drivers/remoteproc/imx_dsp_rproc.c:1110:12: error: 'imx_dsp_suspend' defined but not used [-Werror=unused-function]
 1110 | static int imx_dsp_suspend(struct device *dev)
      |            ^~~~~~~~~~~~~~~

Mark these as __maybe_unused to get a clean build.
