arm64: dts: rockchip: Add reset button to NanoPi R5S
The NanoPi R5S LTS version has a reset button, which is connected via
GPIO. Note that the non-LTS version does not have the reset button and
therefore on page 19 of the schematic version 2204 it is marked 'NC',
but it is connected on the LTS version.
