wifi: mt76: connac: Extend mt76_connac_mcu_uni_add_dev for MLO
[ Upstream commit 9e4c3a007f01f567f2a8af35decd1e3c1c151c0f ]
This commit extends the `mt76_connac_mcu_uni_add_dev` function to include
support for Multi-Link Operation (MLO). Additionally, backward
compatibility for MT7921 is preserved, enabling seamless integration with
existing setups.
Fixes: 86c051f2c418 ("wifi: mt76: mt7925: enabling MLO when the firmware supports it")
