[PATCH v2 1/3] dt-bindings: PCI: mediatek: Add support for EcoNet EN7528

[Caleb James DeLisle <cjd@cjdns.fr>]

Introduce EcoNet EN7528 SoC compatible in MediaTek PCIe controller
binding.

EcoNet PCIe controller has the same configuration model as
Mediatek v2 but is initiallized more similarly to an MT7621
PCIe.
