samd/boards: Add generic SAMD21x18 board definitions.

Browse source 
The definition uses the internal oscillator for clock and only internal
flash for the file system.

It works at SAMD21G18 and SAMD21E18 devices as well, only that fewer pins
are accessible.

Tested with a SAMD21E18, SAM21G18 and SAMD21J18 board.

The following firmware should work on most boards with a SAMD21E18,
SAMD21G18 and SAMD21J18 MCU. It uses only the features built into
the MCU. Additional devices at the board like external flash
are not supported.
