SPI send double buffered, so the DMA completes one byte too early. Use
the recv DMA to know when the SPI transfer is complete.

This includes long delays to avoid overrunning the cc1111 input,
otherwise it works pretty well. The delays mean that we can't capture
the reply to a cmac command though, so more work is needed.

Don't enable DMA in the other direction when doing slave transfers.

Allow either USART in any configuration. Still only supports one SPI
bus though.

Just a comment in the source code about which pins each option selects.

This is untested...

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.

This ensures that the final MOSI pin value will be high after a
receive is finished.

Split out sources into separate directories:
core: architecture and product independent bits
cc1111: cc1111-specific code
drivers: architecture independent drivers
product: product-specific sources and Makefile fragments
util: scripts for building stuff
This should have no effect on the built products, but testing is encouraged
