AFAICT, the link state values are exactly the same as the xHCI link
state values in the Port Link State field in the PORTSC register.  Is
the gadget side (xDCI side) meant to be somewhat compatible with the
xHCI host controller spec?

Would it make sense to share these link state macros (and any other
similar #defines) with the xHCI driver?  We could move them into
include/linux/ch11.h.
