The following is needed to make i.MX compile and work. You renamed
pdata->otg to pdata->xceiv in the driver, but not in the header file.
Renaming it would also mean to rename it in the boards using this
header, that's why I kept the name 'otg' for now instead of renaming
it to 'xceiv' (or 'phy' which I like better).
