[PATCH 1/3] dt-bindings: PCI: ti,j721e-pci-*: Fix check for num-lanes

The existing implementation for validating the "num-lanes" property
based on the compatible(s) doesn't enforce it. Fix it by updating the
checks to handle both single-compatible and multi-compatible cases.

Fixes: b3ba0f6e82cb ("dt-bindings: PCI: ti,j721e-pci-*: Add checks for num-lanes")
Fixes: adc14d44d7cb ("dt-bindings: PCI: ti,j721e-pci-*: Add j784s4-pci-* compatible strings")
