Input: cobalt_btns - switch to using polled mode of input devices

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

Say Y here if you want to support MIPS Cobalt button interface.
