rpmsg: add helper macro module_rpmsg_driver 



This patch introduces the module_rpmsg_driver macro which is a
convenience macro for rpmsg driver modules similar to
module_platform_driver. It is intended to be used by drivers which
init/exit section does nothing but register/unregister the rpmsg driver.
By using this macro it is possible to eliminate a few lines of
boilerplate code per rpmsg driver.
