spi: Add THIS_MODULE to spi_driver in SPI core
Add spi_register_driver helper macro that adds THIS_MODULE to spi_driver for the registering driver. We rename and modify the existing spi_register_driver to enable this. Signed-off-by: Andrew F. Davis <afd@ti.com> Signed-off-by: Mark Brown <broonie@kernel.org>
