On Lager board, i2c and iic cores can be interchanged since they can be
muxed to the same wires. Commit e489c2a9bc82713167d9f721ca764f4b0d37e543
("ARM: shmobile: lager: enable i2c devices") activated the i2c cores,
yet the iic cores should be default since they have the more interesting
features for generic use cases, i.e. SMBUS_QUICK and DMA (yet to be
supported).
