Upstream Linux's input gpio-keys driver supports
specifying a external interrupt for a gpio via the
'interrupts' properties as well as having support
for software debounce.
This patch ports these features to OpenWrt's event
version. Only the "pure" interrupt-driven support is
left behind, since this goes a bit against the "gpio"
in the "gpio-keys" and I don't have a real device to
test this with.
This patch also silences the generated warnings showing
up since 4.14 due to the 'constification' of the
struct gpio_keys_button *buttons variable in the
upstream struct gpio_keys_platform_data declaration.
