68f9916ab6 samd21: spi: fix power regression 
The MISO pin cannot be left floating as it increases power consumption

ea8b90fa5f cpu/samd21: uart: now using padd setting from board config 
Notice the extra fields in uart_conf_t for rx_pad and tx_pad.

Kees Bakker
845ef0decd cpu/samd21: Refactor spi using ArduinoCore as example 
The pinmux is now part of the board config. The pad setting is done with
clear names instead of numbers.

f794bd4c8e cpu/samd21: spi: change #ifdef's to #if's 
The board config can define SPI_1_EN as 0, and in that case #ifdef won't
work.

Add some more comments, and fix typos.

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.

ac3683b09f cpu/samd21:i2c: the wait for SYNCBUSY must come after enable or disable
