firmware: arm_scmi: Add SCMI PM driver remove routine
Currently, when removing the SCMI PM driver not all the resources
registered with genpd subsystem are properly de-registered.
As a side effect of this after a driver unload/load cycle you get a
splat with a few warnings like this:
| debugfs: Directory 'BIG_CPU0' with parent 'pm_genpd' already present!
| debugfs: Directory 'BIG_CPU1' with parent 'pm_genpd' already present!
| debugfs: Directory 'LITTLE_CPU0' with parent 'pm_genpd' already present!
| debugfs: Directory 'LITTLE_CPU1' with parent 'pm_genpd' already present!
| debugfs: Directory 'LITTLE_CPU2' with parent 'pm_genpd' already present!
| debugfs: Directory 'LITTLE_CPU3' with parent 'pm_genpd' already present!
| debugfs: Directory 'BIG_SSTOP' with parent 'pm_genpd' already present!
| debugfs: Directory 'LITTLE_SSTOP' with parent 'pm_genpd' already present!
| debugfs: Directory 'DBGSYS' with parent 'pm_genpd' already present!
| debugfs: Directory 'GPUTOP' with parent 'pm_genpd' already present!
Add a proper scmi_pm_domain_remove callback to the driver in order to
take care of all the needed cleanups not handled by devres framework.
