ARM: dts: omap4-droid4: Fix lost keypad slide interrupts for droid4
We may lose edge interrupts for gpio banks other than the first gpio bank as they are not always powered. Instead, we must use the padconf interrupt as that is always powered. Note that we still also use the gpio for reading the pin state as that can't be done with the padconf device. Signed-off-by: Tony Lindgren <tony@atomide.com>
