[PATCH 2/4] Create and hook up of_platform_device_shutdown

[Michael Ellerman]

Although of_platform_device's can have a shutdown routine, at the moment
the bus code doesn't actually call it. So add the required glue to
hook the shutdown routine.

CC various folks who've written/touched of_platform_drivers which already
have shutdown routines. These routines have never been called so they're
about to get their first testing.
