This adds support for all samd21 variants. Notice that the previous samd21
was moved to cpu/samr21
To use this cpu variant you must set at least the following in your boards
Makefile.include:
export CPU = samd21
export CPU_MODEL = samd21j18a # Not sure if this is used
CFLAGS += -D__SAMD21J18A__ # or whatever variant you have
The samd21 include files were copied from ASF 3.30

CMSIS from Atmel Software Foundation (ASF)
The include files in the directory tree are copied from ASF. See https://spaces.atmel.com/gf/project/asf/frs/?action=FrsReleaseBrowse&frs_package_id=4 (dd. 2016-07-15 ASF version 3.30 was used)
The directory tree was copied "as is" and its structure is as follows:
cmsis
└── samd21
├── include
│ ├── component
│ ├── instance
│ └── pio
└── source
├── gcc
└── iar
There is only one include file (per CPU variant) that should be included in
the source code. For SAMD21 that is cmsis/samd21/include/samd21.h. But
that will only work if the proper define is set. The define is named after
the variant, for example __SAMD21J18A__. This define must be set in the
Makefile.include of the board.
Be aware that if you want to make changes to any file in this tree that the changes will be lost when a new ASF release is going to be used.
