Add Device Tree support for Intel Wi-Fi hardware integration information
on platforms that do not provide UEFI variables or ACPI methods.

Patch 1/3 adds the DT binding schema for the Intel iwlwifi compatible
node. Patches 2/3 and 3/3 add the driver infrastructure and integrate DT
as the lowest-priority fallback after UEFI and ACPI.

Changes in v2:
- Drop mailing list from maintainers in YAML binding
- Drop binding-purpose sentence from description
- Fix dtschema 2026.4 validation errors (items/minItems enforcement)
- Fix yamllint line length violations
- Add driver companion patches (2/3 and 3/3) for reference, showing how
  the binding is consumed by the driver; these will be merged through the
  regular iwlwifi upstreaming process, not through the DT tree
