Input: add input driver for polled GPIO buttons
The existing gpio-keys driver can be usable only for GPIO lines with
interrupt support. Several devices have buttons connected to a GPIO
line which is not capable to generate interrupts. This patch adds a
new input driver using the generic GPIO layer and the input-polldev
to support such buttons.
[Ben Gardiner <bengardiner@nanometrics.ca: fold code to use more
of the original gpio_keys infrastructure; cleanups and other
improvements.]
