arm64: dts: rockchip: Add SOQuartz blade board

This adds a device tree for the PINE64 SOQuartz blade baseboard,
a 1U rack mountable baseboard for the CM4 form factor with PoE
support designed for the SOQuartz CM4 System-on-Module.

The board takes power from either PoE or a 5V DC input, and allows
for mounting an M.2 SSD.

The board also features one USB 2.0 host port, one HDMI output,
a 3.5mm jack for UART, and the aforementioned gigabit networking
port.
