USB: move keyboard polling into kbd driver

Browse Source 
This moves keyboard polling logic from USB HCD drivers into USB
keyboard driver.  Remove usb_event_poll() as keyboard polling was
the only user of this API.  With this patch USB keyboard works with
EHCI controllers again.  Tested on a tegra2 seaboard.
