[PATCH 07/22] Input: jornada680_kbd - switch to using polled mode of input devices

[Dmitry Torokhov]

We have added polled mode to the normal input devices with the intent of
retiring input_polled_dev. This converts jornada680_kbd driver to use the
polling mode of standard input devices and removes dependency on
INPUT_POLLDEV.
