EN7532 is an ARM based platform SoC integrating the same PCIe IP as
MT7622, add a binding for it.

This patch allows selecting the pcie-mediatek driver if ARCH_AIROHA is set,
because the Airoha EN7523 SoC uses the same controller as MT7622.
The driver itself is not modified. The PCIe controller DT node should use
mediatek,mt7622-pcie after airoha,en7523-pcie.

This uses the MediaTek MT7622 PCIe driver, since the PCIe IP block is nearly
identical to the one in MT7622

s/This patch allows/Allow/ ("This patch" is redundant)
For the subject:
PCI: mediatek: Allow building for ARCH_AIROHA
since "controller driver" is similarly redundant and this earlier patch
does essentially the same for a different case:
70060ee313be ("PCI: brcmstb: Allow building for BMIPS_GENERIC")
