[PATCH 04/15] wifi: mt76: mt7925: report only 2.4 GHz NAN supported band

[Sean Wang <sean.wang@kernel.org>]

From: Stella Liu <yu-ching.liu@mediatek.com>

The firmware only checks the 2.4 GHz bit of the local device capability
supported_bands field, so set it directly and drop the unused helper.

Fixes: 0f3605e4f8de ("wifi: mt76: mt7925: wire up NAN operations")
