[PATCH 06/10] i2c-designware: move controller config to bus specific portion of driver

[dirk.brandewie-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org]

From: Dirk Brandewie <dirk.brandewie-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

With multiple I2C adapters possible in the system each running at
(possibly) different speeds we need to move the controller
configuration bit field to the adapter.
