arm64: dts: amlogic: meson-s4-s905y4-khadas-vim1s: add POWER key support
Add the gpio-keys-polled node to support the Power button found on the
Khadas VIM1S board. The button is connected to the GPIOD_8 pin.
Use polled mode instead of gpio-keys because the GPIO interrupt
controller support for Meson S4 SoC is not yet available upstream.
