It's not ready for flight yet, but at least it's sensible now.

The STM32L151 has several SPI busses, and we want to use more than
one, so add a 'bus' parameter to the SPI interfaces. To avoid wasting
time on AVR and CC1111 processors which only use one SPI bus, elide
those parameters from the actual functions by wrapping them with
macros.
Configuring chip select is now all macroized so that each chip can
have its own version, allowing the STM to share the various SPI device
drivers with the cc1111 and avr processors. Note that only the M25
driver has been ported; porting the others is 'trivial', but not
necessary at this point.

Reset doesn't take very long, while doing a conversion seems to take
more than 10ms.

It's loading prom values and converting sensor data, but it's getting
the wrong answer at present.
