arm64: dts: rockchip: Add TS133 variant of the QNAP NAS series

The TS133 is a one-bay NAS mostly similar to the other devices in the
series. The main difference is that it is build around the RK3566 SoC
instead of the RK3568 variant.

The RK3566/RK3568 are mostly similar with only slight variants in both
speed and some specific peripherals - the RK3568 has more.

The specific for the NAS series stay the same though.
