[patch 2.6.27-rc7] i2c: do earlier driver model init

[David Brownell]

From: David Brownell <dbrownell-Rn4VEauK+AKRv+LV9MX5uipxlwaOVQ5f@public.gmane.org>

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.)
