cleanup: Standardize use of CONFIG_I2C and add MASTER/SLAVE CONFIGs

Some chips previously defined CONFIG_I2C and others didn't. Standardize
the usage by removing CONFIG_I2C from all config_chip files and force it
to be defined at the board level. Also, make boards define
CONFIG_I2C_MASTER and/or CONFIG_I2C_SLAVE based on the I2C interfaces
they will use - this will assist with some later cleanup.

TEST=`make buildall -j`
