[PATCH v3 3/5] arm64: dts: qcom: Add Shikra CQ2390M SoM platform

[Komal Bajaj <komal.bajaj@oss.qualcomm.com>]

Add device tree include for the CQ2390M variant of the Shikra
System-on-Module, a compact compute module integrating the Shikra SoC
and PMIC for IoT applications, designed to mount on carrier boards.

  - shikra-cqm-som.dtsi: Retail SoM with modem (PM4125 and PM8005 PMIC)

The DTSI includes the common shikra.dtsi, adds PM4125 and PM8005 PMIC
regulator definitions specific to this variant.
