With the new Kconfig preprocessor (described in
https://github.com/torvalds/linux/blob/master/Documentation/kbuild/
kconfig-macro-language.txt), the syntax for expanding environment
variables is $(FOO) rather than $FOO.
$(FOO) is a general preprocessor variable expansion, which falls back to
environment variables if the variable isn't set (like in Make). It can
also be used in prompts, 'comment's, etc.
The old syntax will probably be supported forever in Kconfiglib for
backwards compatibility, but might as well make it consistent now that
people might start using the preprocessor more.

These are no longer required. Kconfiglib expands references to
environment variables directly.

Add a new test to make I2C transfers between an I2C controller and
an I2C slave driver, either by:
- Using a virtual I2C driver
- Using a physical link and 2 physical controllers
The Physical test uses :
- Two EEPROM Slave drivers each connected to one I2C controller
- Both I2C controllers also act as master and take turns writing
to the opposite EEPROM Slave.
All of this connected physically on the board.
