[PATCH v2 32/37] wifi: mt76: mt7925: update mt7925_mcu_sta_phy_tlv for MLO

[sean.wang at kernel.org]

From: Sean Wang <sean.wang at mediatek.com>

when we serve MLO during the multiple-linked connection, the chanctx may
be not available in the internal driver, we should get the proper the
band information from link_conf for the MLO-enabled firmware.
