Rather than moving towards having more drivers have to be built in (and
depend on their probe order) we need to be moving towards building all
these drivers as modules, including omap-i2c.

There's no reason for board code to have to do this at initcall time.

This kind of thing needs to be done by platform_data function pointers,
as is done for every other driver that needs platform-specific driver
