HID: playstation: convert to use dev_groups

There is no need for a driver to individually add/create device groups,
the driver core will do it automatically for you.  Convert the
hid-playstation driver to use the dev_groups pointer instead of manually
calling the driver core to create the group and have it be cleaned up
later on by the devm core.
