arm64: dts: allwinner: h618: Add Sipeed Longan SoM 3H and Pi 3H board

Add Sipeed Longan SoM 3H and Longan Pi 3H board support.

The Sipeed Longan SoM 3H is a system on module based on the Allwinner H618 SoC. The SoM features:

- Four ARM Cortex-A53 cores, Mali-G31 MP2 GPU
- 2/4 GiB LPDDR4 DRAM SoMs
- AXP313a PMIC
- eMMC

The Sipeed Longan PI 3H is a development board based on the above SoM. The board features:
- Longan SoM 3H
- Raspberry-Pi-1 compatible GPIO header
- 2 USB 2.0 host port
- 1 USB 2.0 type C port (power supply + OTG)
- MicroSD slot
- 1Gbps Ethernet port (via RTL8211 PHY)
- HDMI port
- WiFi/BT chip

Since v2:
- collect Reviewed-by tag
- add vin-supply property to reg_vcc3v3
- fix reg_vcc3v3 voltage value
- remove "interrupt-parent" and "interrupts" properties from axp313 node

Since v1:
- Use const rather than enum for "sipeed,longan-pi-3h" dt-binding
- remove dts-v1, model and compatible from SoM dtsi
- add interrupt related properties to axp313 dt node
- use "vcc-1v8-pll" and "vcc-3v3-io" as regulator name
- add dt node for board's discrete 5V->3.3V regulator and use it for eth\tfcard 3.3v supply
- add usb2_vbus-supply property
