Now that we have a device reference in struct usb_otg
let's use dev_dbg() for debug messages.

Could you squash patch 2 with this one?

We can't because at patch 2, otg->dev is not defined and we need patch 2
before patch 8 to prevent the build warning. This patch can come only
after patch 8 where we add otg->dev.

cheers,
