[PATCH] pmdomain: raspberrypi-power: add remove function

[Gregor Herburger <gregor.herburger@linutronix.de>]

The raspberrypi-power driver registers resources with
of_genpd_add_provider_onecell and pm_genpd_init but never removes them.
When the driver gets unbound and bound again this causes error. Add a
remove function to cleanup all registered resources.
