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.
