[PATCH] i2c: add missing KERN_* constants to printks

[Frank Seidel <fseidel-l3A5Bk7waGM@public.gmane.org>]

From: Frank Seidel <frank-aMRDT+nbkrEb1SvskN2V4Q@public.gmane.org>

According to kerneljanitors todo list all printk calls (beginning
a new line) should have an according KERN_* constant.
Those are the missing pieces here for the i2c subsystem.
