wifi: rtw89: pci: move chip ISR definition out from chip generation

Browse Source 
The existing WiFi 6 chips can share the same ISR (interrupt status
registers), but the coming WiFi 7 chip 8922DE can't share the same
definition with existing WiFi 7 chip, so move the definition to an
individual struct.

Don't change logic at all.
