board: rockchip: add support for Qnap TS433 devices

The Qnap TS433 is a 4-bay NAS based around the RK3568.

Two SATA bays are connected to the RK3568's own SATA controllers while
the other two are connected to a JMicron SATA controller living on the
PCIe bus.

It provides one 2.5Gb and one 1Gb ethernet port as well as 3 usb ports.
