Usually it's better to initialize things later than earlier as
that cuts down nasty dependencies and let's us have a proper
debug console before we start initializing things beyond
interrupts and drivers.
Maybe just fix up the i2c-omap.c not to use subsys_initcall()?
And then deferred probe should be able to sort out the dependencies
for other drivers depending on i2c?

Tony
