arm64: dts: qcom: Add device tree for Longcheer L8150 

Longcheer L8150 is a smartphone based on MSM8916 which is
used in several rebrands like the Snapdragon 410
Android One devices or the Wileyfox Swift.

Add a device tree for L8150 with initial support for:
  - SDHCI (internal and external storage)
  - USB Device Mode
  - UART
  - Regulators
