[PATCH 1/4] 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.

One SoM variant is introduced:
  - CQM: retail variant with integrated modem (PM4125 PMIC)

Two EVK boards are supported:
  - shikra-cqm-evk: pairs with the CQM SoM
  - shikra-cqs-evk: pairs with the CQM SoM, with no modem support

Each EVK provides debug UART, USB, and other peripheral interfaces.

Add compatible strings for the CQM SoM variant and its two
corresponding EVK boards.
