ARM: 9361/1: amba: store owner from modules with amba_driver_register()

Modules registering driver with amba_driver_register() often forget to
set .owner field.  The field is used by some of other kernel parts for
reference counting (try_module_get()), so it is expected that drivers
will set it.

Solve the problem by moving this task away from the drivers to the core
amba bus code, just like we did for platform_driver in
commit 9447057eaff8 ("platform_device: use a macro instead of
platform_driver_register").
