[U-Boot] Disabling CONFIG_DM_I2C_COMPAT in twl4030 PMIC

[Adam Ford]

I am working to disable CONFIG_DM_I2C_COMPAT for the omap3 boards.
Some of these boards use the TWL4030 PMIC which is still using the
older i2c_write and i2c_read functions.

I wonder if someone can point me to a good patch that I can use a
model one how to appropriately port I2C drivers forward?  I'd like to
disable this feature so the notice goes away since it seems like
DM_I2C should be do-able by now.

thanks
