With device core now able to setup the default pin configuration,
the pin configuration code based on the deprecated Samsung specific
gpio bindings is removed.

Hi Doug, Seungwon,
I apologize for the delaying in following up on the review comment.
The setup_bus callback support has been removed in this patch. I did
intend to retain the support for setup_bus callback in the previous
version of this patch since any new platform that might use this
driver and need such a callback would have this callback ready for
use. But it seems removing the setup_bus callback is preferred, so
I am fine with it.
Thomas.
