Javier TiaandFelix Fietkau 3c57528171 wifi: mt76: mt7925: add 320MHz bandwidth to bss_rlm_tlv
bss_rlm_tlv() in mt7925_mcu_bss_rlm_tlv() has no case for
NL80211_CHAN_WIDTH_320. When associated to a 320MHz BSS, the switch
falls through to default and sends bw=0 (CMD_CBW_20MHZ) to firmware
via BSS_RLM TLV. Firmware then configures the RX radio for 20MHz
and cannot decode the AP's 320MHz frames, resulting in complete data
path failure at 320MHz.

Add the missing NL80211_CHAN_WIDTH_320 case with CMD_CBW_320MHZ and
center_chan2.

Tested on ASUS RT-BE92U: 320MHz throughput goes from 0 Mbps to
841 Mbps (iperf3 -t30 -P8), PHY 4803 Mbps EHT-MCS11.
