remoteproc: imx_dsp_rproc: Use devm_pm_runtime_enable() helper

Current code on the cleanup path just disables runtime PM for a device.

Using resource managed version devm_pm_runtime_enable() registers a cleanup
callback that sets autosuspend to false and then disables runtime PM for
a device. So, basically the same functionality as we don't use autosuspend
anyway.

As a result, the .remove callback is no longer needed, reducing boilerplate
code.
