arm64: dts: allwinner: A133: add support for Baijie Helper A133 board

Browse Source 
Baijie Helper A133 board is a development board around Baijie A133 Core
SBC. Features:

- 1/2/4GiB LPDDR4 DRAM
- 8/16/32GiB eMMC
- AXP707 PMIC
- USB-C OTG port in peripheral mode (via onboard hub)
- 2 USB 2.0 ports
- MicroSD slot and on-board eMMC module
- Gigabit Ethernet
- Bluetooth
- WiFi

Add initial support for both the Helper and Core boards, including UART,
PMU, eMMC, USB, Ethernet, LRADC-connected buttons.

UART1 can only be used for Bluetooth module, but BT-WiFi combo Allwinner
AW869A chip has no mainline driver currently.
