[PATCH] ARM: shmobile: kzm9g: use gpio-keys instead of gpio-keys-polled

[Simon Horman]

From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>

6e20a0a429bd4dc07d6de16d9c247270e04e4aa0
(gpio: pcf857x: enable gpio_to_irq() support) supports
gpio_to_irq() on pcf857x driver.
Now, we can use gpio-keys driver instead of gpio-keys-polled.
