ARM: Davinci: Fix I2C build errors

Several Davinci platforms select the I2C EEPROM support, but don't
select I2C support.  This causes I2C EEPROM support to be built into
the kernel, but I2C support may not be configured to be built in.
This leads to linker errors due to missing I2C symbols.

Arrange for I2C to be selected whenever EEPROM_AT24 is selected.
