[PATCH] spi_bitbang(): use overridable setup_transfer() method
A small bug-fix for spi_bitbang: it must always call the setup_transfer function via the overridable pointer, not assume that its spi_bitbang_setup_transfer is sufficient. Otherwise, if all options in the transfers are default (0), the overrided function will never be called. Granted, the function replacing it must call spi_bitbang_setup_transfer, but it might also have other important things to do, even if the second argument (the spi_transfer) is NULL. Tested together with the other patches on the spi_crisv32_sser and spi_crisv32_gpio drivers (not yet in the kernel, will IIUC be submitted as part of the usual arch-maintainer-pushes).
