arm64: dts: allwinner: h6: Add TaiqiCat (TQC) A01 support

TaiqiCat (TQC) A01 is a set-top box powered by an Allwinner H6 SoC,
equipped with an AXP305 PMIC, 1GB LPDDR3 RAM, 8GB eMMC, an AP6212
WiFi/BT combo module, one 100M Ethernet port, one USB 3.0 Type-A port,
one USB 2.0 Type-A port, one Micro USB port, HDMI, SPDIF, Micro-SD, and
infrared input.

It was released by Ultrapower(UQSoft) as a blockchain-based terminal and is
now discontinued and no longer supported.

Hardware schematics are not available at this time; however, the
dts from the vendor firmware is provided for reference [1].

Based on the PCB silkscreen marking "AZW-KT02 2.0", the ODM/OEM
can be confirmed as AZW, and the overall hardware circuit design
is highly similar to the Beelink GS1.

Tested, works:
- debug UART
- status LED
- USB 3.0 Type-A port
- USB 2.0 Type-A port
- Micro USB port (Host)
- MicroSD
- eMMC
- WiFi/Bluetooth
- HDMI video output

Does not work:
- Ethernet (requires AC200 MFD/EPHY driver)
- HDMI audio

Untested:
- SPDIF
- IR receiver
