[PATCH 2/2] wifi: mt76: mt7927: use real monitor vifs for dual-band monitors

[Sean Wang]

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

MT7927 needs monitor interfaces to be passed to the driver as real vifs
so each monitor interface can be configured with its own band context.

This is required to support concurrent 2 GHz and 5 GHz monitor operation
on the same hw.

Keep the existing virtual monitor behavior for older chips.
