wifi: mt76: mt7925: handle 320MHz bandwidth in RXV and TXS

Browse Source 
The RX vector (RXV) and TX status (TXS) parsing in mac.c lack handling
for 320MHz channel width. When the hardware reports 320MHz in the
bandwidth field, mt7925_mac_fill_rx_rate() returns -EINVAL and
mt7925_mac_add_txs_skb() records no bandwidth stats.

Add IEEE80211_STA_RX_BW_320 cases to both functions. The RXV parser
also handles BW_320+1 since the hardware can report 320MHz in two
adjacent encoding positions.
