wifi: mt76: mt7996: add macros for pci device ids

Browse Source 
The chipset name (i.e., brand name) used by the driver may cause confusion
with the PCI device ID when adding support for new chipsets.

| Chipset name | PCI device id  |
|--------------|----------------|
| 7996         | 0x7990, 0x7991 |
| 7992         | 0x7992, 0x799a |
| 7990         | 0x7993, 0x799b |

To prevent confusion, replace the code that directly uses the device ID
with macros. This is a preliminary patch to support mt7990 chipset.
