RFC Create separate header for ehci-dbgp driver

One more attempt at getting some feedback.

Original:

The FUSBH200 and FOTG210 are not EHCI-compatible and require standalone drivers. See discussion at:

http://comments.gmane.org/gmane.linux.usb.general/84169

But these controllers do implement an EHCI-compatible debug port and therefore leverage the ehci-dbgp driver. Rather than pulling in the necessary declarations from <linux/usb/ehci_def.h>, each driver copies this code into their own header. The goal of this series is to pull the ehci-dbgp related code into its own header to remove the need for this redundancy.

I have done only minimal testing on this, and I don't use either of these controller so my ability to test the changes is limited. But I thought I'd push it out for comment to see if there was interest.

The only actual change should be when CONFIG_EARLY_PRINTK_DBGP is disabled and CONFIG_XEN_DOM0 is enabled. Currently each of these does not notify Xen of reset events under this configuration. Since these events are propagated when CONFIG_EARLY_PRINTK_DBGP and CONFIG_XEN_DOM0 are both enabled, though, it seems that is not a problem (and maybe not sending them in the former case is a bug?) Regardless, the motivation for this change is for consistancy as a step towrads consolidation. As I said above, I am not able to actually test these changes on either controller.

First time submission, so I look forward to any feedback. If this is of any interest I will work on testing the various configations and boot parameters.
