Ruslan Popov 619560c112 I2C: initial support. 
This commit squashes in some fixes found after debugging on the
topic branch. Test code by Traumflug, collected from Ruslan's
code on the topic branch.

Before, same as now without I2C:

    FLASH  : 22408 bytes
    RAM    :  1393 bytes
    EEPROM :    32 bytes

Now with I2C:

    FLASH  : 23224 bytes
    RAM    :  2057 bytes
    EEPROM :    32 bytes

This totals to some 800 bytes with a whole lot of test code, so
implementation is pretty small :-)

Markus Hitter d2fcc57ed4 Introduce #ifdef SPI. 
It's better to separate this by function than by usage.

Markus Hitter d337fd18ad mendel.c: move CPU initialisation to cpu.c (cpu-avr.c). 
No functional change, but more code separated by architecture.

Markus Hitter 575174940f ARM: get a minimum amount of Teacup compiled for ARM. 
Makefile can't even upload, yet.
