429c78f9b0 ANDROID: GKI: device.h: add Android ABI padding to some structures 
Try to mitigate potential future driver core api changes by padding to
struct bus_type, struct device_driver, struct class, and struct device.

Based on a patch from Michal Marek <mmarek@suse.cz> from the SLES kernel

54539dfef4 ANDROID: GKI: add some padding to some driver core structures 
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

a8ae608529 device.h: move 'struct class' stuff out to device/class.h 
device.h has everything and the kitchen sink when it comes to struct
device things, so split out the struct class things things to a separate
.h file to make things easier to maintain and manage over time.
