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.)
