[PATCH 02/13] platform: add a dev_groups pointer to struct platform_driver

[Greg Kroah-Hartman]

As the driver core now provides the ability to directly add/remove
device groups when a driver is bound/unbound to a device, just pass that
pointer along to the driver core.

This allows us to fix up platform drivers to not need to create/remove
groups "by hand" anymore.
