All the macro arguments that are user supplied, or potentially, wrap properly
in () as good practice.
Probably missed one or two, and a lot of them are possibly unnecessary, but
it's straightforward to just do it always.
Fixes github issue #321
Latest versions of all reference manuals refer to the address as SPIx_BASE, and
simply name some of the individual registers as SPI_I2SXXXX. Likewise, the
interrupts are simply SPIx, not SPIx/I2Sx. Rather than hacking more duplicates
into the F0 and L0 parts where this was turning up, remove the pointless _I2S_
from SPI2/SPI3 and make it all consistent
Compile tested only, with the examples collection.

The common code wasn't being included in L1 builds, even though the headers now
included the correct definitions.
This combines the two f0 and f3 spi files, which previously differed only in
the number of spi peripherals defined.
Files were renamed to the full "l1f124" style, not because I like it, but
because it's the convention we have, so it's best to apply it rigourously.
Tested on L1 and F100 boards, compile tested only for others, but the examples
repository all compiles too. (Though the lack of SPI examples for all
platforms was how this broke in the first place)
