[PATCH 3/3] arm64: dts: allwinner: h618: add Transpeed 8K618-T TV box

This is a Chinese TV box, probably very similar if not identical to
various other cheap TV boxes with the same specs:
- Allwinner H618 SoC (4 * Arm Cortex-A53 cores, 1MB L2 cache)
- 2 or 4GiB DDR3L DRAM
- 32, 64, or 128 GiB eMMC flash
- AXP313a PMIC
- 100 Mbit/s Ethernet (using yet unsupported internal PHY)
- HDMI port
- 2 * USB 2.0 ports
- microSD card slot
- 3.5mm A/V port
- 7-segment display
- 5V barrel plug power supply

The PCB provides holes for soldering a UART header or cable, this is
connected to the debug UART0. UART1 is used for the Bluetooth chip,
although this isn't working yet.
