i2c: designware: add SLAVE mode functions
- Changes in Kconfig to enable I2C_DESIGNWARE_SLAVE support
- Slave functions added to core library file
- Slave abort sources added to common source file
- New driver: i2c-designware-slave added
- Changes in the Makefile to compile the I2C_DESIGNWARE_SLAVE module
when supported by the architecture.
All the SLAVE flow is added but it is not enabled via platform
driver.
