be1113fa6c cpu/sam21_common: move i2c.c from samd21 to sam21_common 
Notice that saml21 does not use I2C (yet).

4ad3313ae5 cpu/sam21_common: add a few typedefs for SERCOM 
A generic function is added to initialize a SERCOM.

Notice that uart_conf_t was expanded with pad settings, but it isn't used
yet.

8644b5f7a0 cpu/samd21: introduce sam0.h so that we can select samr21.h or other 
In the Makefile.include of the board it is required to set the correct
define.

Currently only SAMRG18A is supported, as required by samr21-xpro.

88e84f68ff cpu/sam21_common: update ASF CMSIS (samr21) include files using ASF 3.21 
Notice that RIOT was using FDPLL96M, which is indeed the name in the
datasheet. But Atmel is using GCLK_GENCTRL_SRC_FDPLL.

e0365e0bf9 atmega: use software interrupt for context swap 
Fixes #5745
For AVR based boards, three defines must be defined AVR_CONTEXT_SWAP_INIT,
AVR_CONTEXT_SWAP_INTERRUPT_VECT, and AVR_CONTEXT_SWAP_TRIGGER.
These defines are used to trigger a software interrupt used for context
switching.

When AVR_CONTEXT_SWAP_INTERRUPT_VECT is handled, the scheduler is run
and a context swap will happen if necessary, with the resulting thread
starting following the reti instruction. This results in threads running
at normal priority instead of at interrupt priority.

Atmega devices do provide a pure software interrupt. The method used
here for waspmote-pro and arduino-mega2560 is to use pin change
interrupts, set the pin to act as an output, and toggle the value to
simulate a software interrupt. The main limitation here is that a
physical pin is now occupied and must be defined for each board
supported by RIOT. On the plus side, it provides an easy method for
detecting context swaps with an oscilloscope.

eed73beaa1 cpu/atmega_common: prepare for atmega328p inclusion 
use generic avr/libc definition for conditionnal compilation.
eg: use #ifdef(PORTG) or #ifdef(TIMER_0_ISRC) instead of #ifdef(Atmega328p)
This is more generic and simplify future boards support.
