Subjectc2port (Version 2): support for Silicon C2 Interface.
C2 port implements a two wire serial communication protocol (bit
banging) designed to enable in-system programming, debugging, and
boundary-scan testing on low pin-count Silicon Labs devices.

Main references are at Silicon Laboratories site:

* AN127: FLASH Programming via the C2 Interface
http://www.silabs.com/public/documents/tpub_doc/anote/Microcontrollers/Small_Form_Factor/en/an127.pdf

* C2 Specification
http://www.silabs.com/public/documents/tpub_doc/spec/Microcontrollers/en/C2spec.pdf

Currently this code supports only flash programming through sysfs
interface but extensions shoud be easy to add.

Changelog
---------

Version 1 -> 2:

* Documentation added.

* One client added.
