arm64: dts: rockchip: add PX30-µQ7 (Ringneck) SoM with Haikou baseboard 

The PX30-uQ7 (Ringneck) SoM is a µQseven-compatible (40mmx70mm, MXM-230
connector) system-on-module from Theobroma Systems[1], featuring the
Rockchip PX30.

It provides the following feature set:
 * up to 4GB DDR4
 * up to 128GB on-module eMMC (with 8-bit 1.8V interface)
 * SD card (on a baseboard) via edge connector
 * Fast Ethernet with on-module TI DP83825I PHY
 * MIPI-DSI/LVDS
 * MIPI-CSI
 * USB
   - 1x USB 2.0 dual-role
   - 3x USB 2.0 host
 * on-module STM32 Cortex-M0 companion controller, implementing:
   - low-power RTC functionality (ISL1208 emulation)
   - fan controller (AMC6821 emulation)
   - USB<->CAN bridge controller
 * on-module Espressif ESP32 for Bluetooth + 2.4GHz WiFi
 * on-module NXP SE05x Secure Element
