include: convert various register fcns to macros to avoid include chaining
The original implementations reference THIS_MODULE in an inline. We could include <linux/export.h>, but it is better to avoid chaining. Fortunately someone else already thought of this, and made a similar inline into a #define in <linux/device.h> for device_schedule_callback(), [see commit 523ded71de0] so follow that precedent here. Also bubble up any __must_check that were used on the prev. wrapper inline functions up one to the real __register functions, to preserve any prev. sanity checks that were used in those instances.
