SPI protocol drivers can submit messages specifying needed bits_per_word parameter for a message transfer. The bitbang driver currently ignores bits_per_word given by a singe message and always uses master's bits_per_word parameter. Only use master's bits_per_word when a message didn't specify needed bits_per_word for ongoing transfer.
