Subject: [PATCH v3 2/4] dt-bindings: serial: renesas,scif: Validate 'interrupts' and 'interrupt-names'

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Add support to validate the 'interrupts' and 'interrupt-names' properties
for every supported SoC. This ensures proper handling and configuration of
interrupt-related properties across supported platforms.
