Move I2C driver model init earlier in the boot sequence.
This avoids oopsing in statically linked systems when some
subsystems register I2C drivers in subsys_initcall() code,
but those subsystems are linked (and initialized) before I2C.

Patch applied, thanks. Will go in 2.6.28, NOT 2.6.27 (too late there
for such a change.)
