[PATCH v2 0/3] PCI: mediatek: Add support for EcoNet SoCs

[Caleb James DeLisle]

Add EcoNet EN7528 (and EN751221) PCIe support.

Changes from v1:
* mediatek-pcie.yaml slot0 needs device-type = "pci", fix dt_binding_check

This was split from a larger PCIe patchset which crossed multiple
subsystems. I'm not labeling this a v3 because it's a new patchset, but
I'm keeping the historical record anyway.

Changes from econet-pcie v2:
* mediatek-pcie.yaml add missing constraints to PCI node properties
* econet-pcie v2: https://lore.kernel.org/linux-mips/20260309131818.74467-1-cjd@xxxxxxxx

Changes from econet-pcie v1:
* pcie-mediatek.c Exclude pcie_retrain_link() when building as a module
* econet-pcie v1: https://lore.kernel.org/linux-mips/20260303190948.694783-1-cjd@xxxxxxxx/
