[PATCH v2 13/13] wifi: mt76: mt7925: enable MT7927 PCI device IDs

Add PCI device table entries for MT7927 hardware variants:
  - 14c3:7927 (ASUS ROG Crosshair X870E Hero, Lenovo Legion Pro 7)
  - 14c3:6639 (Foxconn/Azurewave modules)
  - 14c3:0738 (AMD RZ738 / MediaTek MT7927)

This is the final patch in the series, enabling MT7927 device
enumeration after all infrastructure (DMA, IRQ, HW init, band index,
power management) is in place.
