wifi: mt76: connac: add MT7991A (0x7991) to is_mt7996()

Browse Source 
The MT7991A chipset uses PCI device ID 0x7991 (MT7996_DEVICE_ID_2),
but is_mt7996() only checks for 0x7990. This causes MT7991A devices
to use incorrect chip-specific settings, such as:
- MSDU_CNT_V2 instead of MSDU_CNT in TX descriptors
- Wrong WTBL BMC size (32 instead of 64)
- Incorrect prefetch depth for MCU queues
