usb: Create separate header for ehci-dbgp
The FUSBH200 and FOTG210 controllers implement sufficiently EHCI-
compatible debug ports to leverage ehci-dbgp from their respective
drivers. Rather than including <linux/usb/ehci_def.h> header, though,
they replicate the necessary declarations in their own headers. Move
the ehci-dbgp stuff into its own header as a first step towards removing
this redundancy.
