remoteproc: imx_rproc: Fix runtime PM cleanup and improve remove path

Proper cleanup should be done when rproc_add() fails by invoking both
pm_runtime_disable() and pm_runtime_put_noidle() to avoid leaving the
device in an inconsistent power state.

Fix it by adding pm_runtime_put_noidle() and pm_runtime_disable()
in the error path.

Also Update the remove() callback to use pm_runtime_put_noidle() instead of
pm_runtime_put(), to clearly indicate that only need to restore the usage
count.
