ehci: clear suspend bit on detach
When a device is detached, clear the suspend bit (PORTSC_SUSPEND)
in the port status register.
The specs are not *that* clear what is supposed to happen in case
a suspended device is unplugged. But the enable bit (PORTSC_PED)
is cleared, and the specs mention setting suspend with enable being
unset is undefined behavior. So clearing them both looks reasonable,
and it actually fixes the reported bug.
