spi: bitbang: Make setup_transfer() callback optional
[ Upstream commit 7d0ec8b6f40b356f780b79de63eeafd6b907d68c ]
Some controller drivers have no need of this callback (spi-altera even
causes a NULL pointer dereference because it doesn't register the callback,
falsely assuming that it is already optional).
Fixes: 30af9b558a56 ("spi/bitbang: Drop empty setup() functions")
