dm: i2c: tegra: Convert to driver model
This converts all Tegra boards over to use driver model for I2C. The driver is adjusted to use driver model and the following obsolete CONFIGs are removed: - CONFIG_SYS_I2C_INIT_BOARD - CONFIG_I2C_MULTI_BUS - CONFIG_SYS_MAX_I2C_BUS - CONFIG_SYS_I2C_SPEED - CONFIG_SYS_I2C This has been tested on: - trimslice (no I2C) - beaver - Jetson-TK1 It has not been tested on Tegra 114 as I don't have that board. Acked-by: Heiko Schocher <hs@denx.de> Signed-off-by: Simon Glass <sjg@chromium.org>
