usb: pass USBEndpoint to usb_wakeup

Browse source 
Devices must specify which endpoint has data to transfer now.
The plan is to use the usb_wakeup() not only for remove wakeup support,
but for "data ready" signaling in general, so we can move away from
constant polling to event driven usb device emulation.
