Tegra30: fdt: Update DT files with I2C info for T30/Cardhu
Note that T30 does not have a separate/different DVC (power I2C)
controller like T20 - all 5 I2C controllers are identical, but
DVC_I2C is still used to designate the controller intended for
power control (PWR_I2C in the schematics). On Cardhu, it's used
to access the PMU and EEPROM, as well as the audio codec, temp
sensor, and fuel gauge devices from the OS.
