spicmds: Rework spi config commands
...
Rework the spi_config commands so that bus configuration and shutdown
message configuration is done separately from the main "config_spi"
command. This makes the spi configuration more flexible. It's now
possible to use software spi without a CS pin. It's now possible to
define multiple SPI messages to send on a shutdown event.
