Kill central list of SPI programmers
Remove the array spi_programmer, replace it by dynamic registration
instead. Also initially start with no busses supported, and switch to
the default non-SPI only for the internal programmer.
Also this patch changes the initialization for the buses_supported variable
from "everything-except-SPI" to "nothing". All programmers have to set the
bus type on their own, and this enables register_spi_programmer to just add
the SPI both for on-board SPI interfaces (where the internal programmer
already detected the other bus types), as well as for external programmers
(where we have the default "none").
