cpu/samd21: rewrite i2c_init_master to make use of gpio_init_sercom
...
The former i2c_init_master was too complicated. It was trying to set IN/OUT
mode of the pins, but all that is needed is to set the proper MUX.
Also the configuration for the boards was incomplete (no MUX, no pad
setting).
It was tested on a SODAQ Autonomo, but not on a samr21-xpro

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

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.

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.

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.
