ARM: 7362/1: AMBA: Add module_amba_driver() helper macro for amba_driver

For simple modules that contain a single amba_driver without any
additional setup code then ends up being a block of duplicated
boilerplate. This patch adds a new macro, module_amba_driver(),
which replaces the module_init()/module_exit() registrations with
template functions.
