I've simplified the SPI module, since we only ever use SPI1 (and there
were already a number of places which assumed this was true).
Somewhere along the way I fixed a number of problems keeping the code
from compiling and working on STM32L. The code isn't currently used
anywhere else, but should still work there (that is, I don't think I
broke it working on STM32F if you re-enable it on some STM32F
platform).
