arm64: dts: rockchip: Add green power LED to rk3588s-rock-5a

The Radxa ROCK 5A board includes a green power LED that is defined in
the vendor device tree but is missing from the upstream kernel DTS file.

This causes the LED to be uncontrollable from the operating system, as no
entry is created for it under /sys/class/leds.

This patch adds the missing node to the leds block, creating a
"green:power" device and allowing the LED to be controlled by the kernel.
