usbhost: manage endpoints by library + get/set_toggle → reset_toggle

That simplifies things A LOT. Now you can find endpoints for device in
an array inside device. This array is managed automatically in
register/unregister endpoint. HC drivers still needs to write to it when
setting up/tearing down the device.

Sorry for these two changes being in one commit, but splitting them
would be simply more work for no benefit.
