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.

Changes in v2:
- Adjust tegra_i2c_child_pre_probe() to permit generic I2C devices
- Correct the compatible strings for I2C buses
- Don't init if the speed is 0, since this breaks the controller
- Expand coverage to all Tegra boards
