Although this fixes I2C build errors, it leaves these errors:

arch/arm/mach-davinci/built-in.o: In function `phy_read':
include/linux/phy.h:454: undefined reference to `mdiobus_read'
arch/arm/mach-davinci/built-in.o: In function `phy_write':
include/linux/phy.h:469: undefined reference to `mdiobus_write'
arch/arm/mach-davinci/built-in.o: In function `davinci_evm_init':
arch/arm/mach-davinci/board-dm644x-evm.c:708: undefined reference to `phy_register_fixup_for_uid'

which also look like a configuration problem.
