Subject: [PATCH v3 4/4] dt-bindings: PCI: mediatek,mt7621-pcie: switch from deprecated pci-bus.yaml

dtschema package with core schemas deprecated pci-bus.yaml schema in
favor of individual schemas per host, device and pci-pci.

Switch Mediatek MT7621 PCIe host bridge binding to this new schema.

This requires dtschema package newer than v2024.02 to work fully.
v2024.02 will partially work: with a warning.

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>

---

Important: This depends on change recently merged to dtschema, however
no release was yet made with mentioned change.
Therefore this patch probably should wait a bit. Previous patches do not
depend anyhow on future release, so they can be taken as is.

Changes in v3:
1. None

Changes in v2:
1. New patch
2. Split mediatek,mt7621-pcie to separate patch as it uses
   pci-pci-bridge schema.
