Kevin O'Connor c3efcd9c8d bus: Set all SPI CS pins high before first config_spi message ...

If an SPI device is shared among many devices, then all the device's
CS pins should be set high prior to setting up the clk pin.
(Otherwise, there's a chance a device could interpret the clk pin
setup as part of a transmission.)
