Subject: [PATCH RESEND v2 3/3] arm64: dts: qcom:
 msm8916-xiaoxun-jz0145-v33: Add initial device tree

From: Ricky Cheung <rcheung844@...il.com>

This commit implements support for the JZ0145 v33 WiFi/LTE dongle
based on MSM8916, which was sold by XiaoXun BiCheng Technology.

The stock bootloader could boot with this patch with lk2nd, but only
one CPU core would be enabled. Enablement for all CPU cores require
lk1st and d410c firmware files.

Currently supported / tested:
- All CPU cores
- Buttons
- LEDs
- Modem
- SDHC
- USB Device Mode

Although I do not have UART equipment on hand, UART should function
and is labelled on the PCB of this device.
