Chris Rorvick 895baf2404 fusbh200: Make Xen notificaiton consistent with EHCI 
If CONFIG_XEN_DOM0 is enabled, the ehci-dbgp driver notifies Xen of
controller reset events via xen_dbgp_reset_prep() and
xen_dbgp_external_startup() (via calls to xen_dbgp_op().)  Otherwise
<linux/usb/ehci_def.h> defines them as no-ops to disable this logic.

The fusbh200 driver copies much of the dbgp code from ehci_def.h, but it
unconditionally defines the Xen hooks as no-ops, effectively disabling
these notifications when CONFIG_EARLY_PRINTK_DBGP is disabled.  When
enabled, though, notifying Xen is dependent on CONFIG_XEN_DOM0 due to
fusbh200 leveraging the ehci-dbgp driver.

The following table compares the implementations of xen_dbgp_reset_prep()
and xen_dbgp_external_startup() in the ehci-dbgp and fusbh200 drivers
under the relevant configurations:

  EARLY_PRINTK_DBGP?  XEN_DOM0?  ehci-dbgp      fusbh200
  ------------------  ---------  -------------  -------------
  n                   n          no-op          no-op
  n                   y          xen_dbgp_op()  no-op
  y                   n          no-op          no-op
  y                   y          xen_dbgp_op()  xen_dbgp_op()

This suggests that fusbh200 is, at best, indifferent to whether Xen is
notified of these events.  Make fusbh200 consistent with ehci-dbgp as a
step towards consolidating this code duplication.
