Implement NAN_UNI_CMD_UPDATE_PHY_SETTING (tag=18) to configure the
BSS-level PHY parameters that the FW NAN scheduler uses when it
switches channels.
The command carries separate 2G and 5G PHY settings, each with its
own phy type, rate sets and protection modes.

Forward NAN Unaligned Window attributes between FW and mac80211:
report ULW updates from FW via cfg80211_nan_ulw_update() and push
peer ULW attributes to FW with NAN_UNI_CMD_UPDATE_ULW.

Send a zero avail_map CRB TLV before the peer record deactivation
command. This ensures FW clears the committed schedule slots for
the departing peer, preventing stale CRB entries from affecting
subsequent NDP connections.

Fill avail_map for all DW intervals instead of only DW index 0.
FW requires the bitmap to be set across all 16 DW intervals for
correct NAN scheduling. Without this, NDP ping latency is extremely
high (~200ms) because FW only schedules data in the first DW interval.
Also set ch_type = 1 for new channel entries to indicate
channel-based (non-band) availability.

Handle the NAN DW start event instead of the DW end event for DW
notification. Queuing NDP action frames at the beginning of the DW
window, rather than after it ends, improves NDP handshake reliability.

Refactor mt7925_nan_enable() to build the MCU command from separate
TLVs via skb instead of inline fields in the enable request struct.
The cluster ID, DW interval, discovery beacon interval and RSSI
threshold settings are now shared with mt7925_nan_change_configure()
through the common TLV helpers, avoiding duplicated setup code.

NAN operates with OFDM and does not support CCK, so the phy, rate
control and BSS rate TLVs must not fall back to 2.4 GHz. Borrow the
5 GHz band lookup to keep the STA records OFDM-only.

The committed CRB timeline carried a local_map_id byte that does not
exist in the firmware NAN_SCHEDULE_TIMELINE_T layout (map id plus 3
reserved bytes), shifting the availability bitmap. Drop it and match
the firmware structure.
The common-slot check is also dropped as redundant: mac80211 already
tracks common slots, so avail_map is built directly from the peer
schedule.

The NDP STA record role_idx must carry the NAN BSS band0 index
rather than the mac80211 BSS index, otherwise the firmware maps the
NDP peer to the wrong role. Use the fixed NAN_BSS_INDEX_BAND0 value.
While at it, drop the inline peer-schedule setup in
mt792x_nan_map_sta_rec(): the peer schedule is already driven by the
upper layer through the peer_sched_changed callback
(mt792x_nan_set_peer_schedule()), so the redundant call and the
now-unused local variables are removed.
