arm64: dts: rockchip: Fix cover detection on PineNote

The SW_MACHINE_COVER switch event was added to input event codes to
detect the removal of the back cover of the N900.
But on the PineNote its purpose is to detect when the front cover gets
closed, just like when a laptop lid is closed. Therefore SW_LID is the
appropriate linux code and not SW_MACHINE_COVER.
