mtd: Add helper macro for register_mtd_blktrans boilerplate 



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