include/device: Split i2c.h into three Split `i2c.h` into three pieces to ease reuse of the generic defi- nitions. No code is changed. * `i2c.h` - keeps the generic definitions * `i2c_simple.h` - holds the current, limited to one controller driver per board, devicetree independent I2C interface * `i2c_bus.h` - will become the devicetree compatible interface for native I2C (e.g. non-SMBus) controllers Change-Id: I382d45c70f9314588663e1284f264f877469c74d Signed-off-by: Nico Huber <nico.huber@secunet.com> Reviewed-on: https://review.coreboot.org/20845 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Aaron Durbin <adurbin@chromium.org>
