Add generic access ops for controllers with a ulpi viewport register

I can see mxc, msm and langwell are using the same bits
(or at least some of them).
They all use the Chipidea/ARC usb controllers.
Is there some kind of specification for this ulpi viewport register?
You can find the Chipidea/ARC datasheet in IMX35 datasheet ( got 0x0170
ULPI VIEWPORT) or a newer version (extra fields in some registers but
miss 0x168-0x170) in
