arm64: dts: qcom: msm8916-vivo-y21l: Add initial device tree

Vivo Y21L is a handset using the MSM8916 SoC released in 2016.

Add device tree with initial support for:
 - Accelerometer
 - Ambient Light
 - GPIO keys
 - Magnetormeter
 - SDHCI (internal and external storage)
 - UART
 - USB Device Mode
 - WCNSS (WiFi/BT)
 - Regulators
