arm64: dts: qcom: Add Shikra CQ2390M SoM platform

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
peripheral definitions specific to this variant. Since PM8005 regulators
are controlled by rpmpd, so disabling the pm8005 regulators.
