From: Luis Oliveira <redacted>

Add support in existing I2C Designware Core driver for I2C slave mode. 
Refactored *_master() functions out of existing ones in the first patch
Added *_slave() functions to enable Slave mode. 
Updated the description of the i2c-designware.txt and changed Kconfig to 
auto enable I2C Slave support.

V2: Splitted the patch in *_master() and *_slave() and updated Kconfig.
