i2cdev: New recipe with i2c tools

The main part is the tool lsi2c to scan the i2c bus, like lspci and lsusb
do.

This recipe also ships a static library *libi2cdev.a*. Because this library
contains the file *smbus.c* which is *GPL v2+,* and a static library can't
be linked dynamically to satisfy the LGPL, the whole recipe is marked
as *GPL-2.0-or-later.*
