For arm boards with an i2c bus which a user could reasonably
want to plug arbitrary devices, add 'imply I2C_DEVICES' to the
Kconfig stanza.

Again, slightly arbitrary but erring on the side of conservative.
I leave non-Arm architectures out (afaict only ppc ppc4xx and e500
enable any kind of I2C controller in their Kconfig anyway).
