SPI: Add helper macro for spi_driver boilerplate
This patch introduces the module_spi_driver macro which is a convenience macro for SPI 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 SPI driver. By using this macro it is possible to eliminate a few lines of boilerplate code per SPI driver.
