dm: i2c: Add a uclass for I2C
The uclass implements the same operations as the current I2C framework but makes some changes to make it fit driver model better: - Remove the chip address from API calls - Remove the address length from API calls - Remove concept of 'current' I2C bus - Drop all existing init functions Acked-by: Heiko Schocher <hs@denx.de> Reviewed-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Signed-off-by: Simon Glass <sjg@chromium.org>
