arm64: dts: qcom: Add SDM660 SoC support 

Initial device tree support for Qualcomm SDM660 SoC.

SDM660 is based off MSM8998 and uses some of its drivers.
SDM630/636 are based off SDM660 SoC and they are pin
and software compatible.

The device tree is based on the CAF 4.4 kernel tree.

Features:
 * CPU nodes
 * Timer nodes
 * Interrupt controller
 * Global Clock Controller
 * Top Level Mode Multiplexer (pin controller)
 * UART node

This is inspired by and based on the work of Craig Tatlor in
https://patchwork.kernel.org/patch/10563667/
