[PATCH 2/4] arm64: dts: allwinner: h700: Add RG35XX 2024 DTS

[Ryan Walklin <ryan@testtoast.com>]

From: Ryan Walklin <ryan@testtoast.com>

The base model RG35XX (2024) is a handheld gaming device based on an Allwinner 
H700 chip.

The H700 is a H616 variant (4x ARM Cortex-A53 cores @ 1.5Ghz with Mali G31 GPU) 
which exposes RGB LCD and NMI pins.

Device features:
- Allwinner H700 @ 1.5GHz
- 1GB LPDDR4 DRAM
- X-Powers AXP717 PMIC
- 3.5" 640x480 RGB LCD
- Two microSD slots
- Mini-HDMI out
- GPIO keypad
- 3.5mm headphone jack

Enabled in this DTS:
- AXP717 PMIC with regulators (interrupt controller TBC/TBD)
- Power LED (charge LED on device controlled directly by PMIC)
- Serial UART (accessible from PIN headers on the board)
- MMC slots
