Log Message:
ehci(4): properly handle failed attach
thinkpad a475 fails to attach an ehci instance:
ehci0: pre-2.0 USB rev, device ignored
which ends up stopping suspend/resume working as the device has no
pmf handlers installed. put most of the teardown code into a new
common function that is called from failed attach and detach. if
attach fails, register NULL pmf handlers. don't check the return
value of pmf_device_register*().
re-order several parts of detach to match the reverse attach order.
tested on rockpro64, thinkpad a475, and xps 1645, the a475 can now
suspend/resume almost fully successfully.
