Since the pmic8xxx-pwrkey driver is already supported in the
qcom-apq8064.dtsi, and the pmic8xxx-pwrkey supports logic to
configure proper device shutdown when ps_hold goes low, it is
better to use that driver then a generic gpio button.

Thus this patch remove the gpio power key entry here, so we
don't get double input events from having two drivers enabled.

The one gotcha with the pmic8xxx-pwrkey is it has a fairly
long debounce delay, which we shorten here to make the button
behave as expected.
