Input: rb532_button - switch to using polled mode of input devices 

We have added polled mode to the normal input devices with the intent of
retiring input_polled_dev. This converts rb532_button driver to use
the polling mode of standard input devices and removes dependency on
INPUT_POLLDEV.

Say Y here if you want support for the S1 button built into
Mikrotik's Routerboard 532.
