greybus: svc: add intf_eject attribute
Add a new write-only svc attribute to send an eject request to the svc
giving the interface number.
So, doing:
echo 3 > /sys/bus/greybus/devices/1-svc/intf_eject
will force eject the module on interface 3 (module slot 1 on EVT1).
This can take some seconds as the pulse width for module release is
large.
