Subject: [PATCH 1/2] mt76: mt7663: fix up BMC entry indicated to unicmd firmware

From: Sean Wang <[email protected]>

BMC entry for MT7663 unicmd firmware should be a broadcast/multicast entry,
not a unicast entry, that is GTK rekey offload would rely on.

Fixes: 138860679b2a ("mt76: mt7615: add more uni mcu commands")

v1->v2:
mt7615_mcu_uni_add_bss is only called on mt7663 with the offload firmware,
so remove the entire unnecessary if code section.
