This sets up the device clock rate, SPI mode, and word sizes.
Drivers may change the defaults provided by board_info, and then
call spi_setup(spi) to invoke this routine. It may sleep.
Unless each SPI slave has its own configuration registers, don't
change them right away ... otherwise drivers could corrupt I/O
that's in progress for other SPI devices.
** BUG ALERT: for some reason the first version of
** many spi_master drivers seems to get this wrong.
** When you code setup(), ASSUME that the controller

This must not sleep. Its responsibility is arrange that the
transfer happens and its complete() callback is issued. The two
