[PATCH] SPI: Renamed bitbang_transfer_setup to spi_bitbang_setup_transfer and export it

Renamed bitbang_transfer_setup to follow convention of other exported symbols
from spi-bitbang.  Exported spi_bitbang_setup_transfer to allow users of
spi-bitbang to use the function in their own setup_transfer.
