Enable I2C support for sandbox. This is an emulation of a real I2C
bus. Devices can be attached to the bus using the device tree
- which specifies the driver to use. As an example, see this device
- tree fragment from sandbox.dts. It shows that the I2C bus has a
- single EEPROM at address 0x2c (7-bit address) which is emulated by
- the driver for "sandbox,i2c-eeprom", which is in
- drivers/misc/i2c_eeprom_emul.c.
