[POWERPC] Fix windfarm platform device usage
The windfarm code uses a struct device_driver instead of platform_driver, which can cause crashes if any of the callbacks are called (like on module removal). This fixes it. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
