ANDROID: GKI: add some padding to some driver core structures

Browse Source 
These structures are fundamental to implementing fw_devlink and
sync_state(). Since they are still evolving, add some padding in case we
need to backport any important bug fixes.

	struct device_link
	struct class
	struct fwnode_handle
	struct fwnode_link
