Converting drivers to use spi_controller everywhere in lieu of
spi_master is fine, but drivers need to specify whether the
spi_controller is a master or a slave and Geert's design is
to specify that on allocation.  Which makes sense because
that's the moment the spi_controller comes to life, there's
no earlier moment where one could specify the type.

Thanks,

Lukas
