USB: move keyboard polling into kbd driver
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. Signed-off-by: Allen Martin <amartin@nvidia.com>
