[PATCH] Documentation/i2c: direct users to i2c-tools regarding i2c/smbus.h

[Sam Hansen <hansens@google.com>]

The current examples reference i2c/smbus.h, which is the first reference
in Documentation/i2c/dev-interface to anything related to the i2c-tools
project.  This moves the existing reference to i2c-tools up into the
C-example, directing the user to the project's git repository.
