[PATCH v4 1/5] dt-bindings: arm: qcom: Document Shikra and its EVK boards

[Komal Bajaj]

Shikra is a Qualcomm IoT SoC available in a System-on-Module (SoM)
form factor. The SoM integrates the Shikra SoC, PMICs, and essential
passives, and is designed to be mounted on carrier boards.

Three eSoM variant are introduced:
  - CQM: retail variant with integrated modem (PM4125 and PM8005 PMIC)
  - CQS: retail variant without modem (PM4125 and PM8005 PMIC)
  - IQS: industrial-grade variant without modem (PM8150 PMIC)

Each SoM variant pairs with a common EVK carrier board provides debug
UART, USB, and other peripheral interfaces.

Add compatible strings for the CQ2390M, CQ2390S, IQ2390S SoM variant and
its corresponding EVK boards.
