Update two points in the SPI interface documentation: - Update description of the "chip stays selected after message ends" mode. In some cases it's required for correctness; it isn't just a performance tweak. (Yes: to use this mode on mult-device busses, another programming interface will be needed. One draft has been circulated already.) - Clarify spi_setup(), highlighting that callers must ensure that no requests are queued (can't change configuration except between I/Os), and that the device must be deselected when this returns (which is a key part of why it's called during device init).
