Subject: wl12xx: FM WLAN coexistence

Add support to FM WLAN coexistence (STA only).  Some WiFi harmonics
may interfere with FM operation, to avoid this problem special
coexistence techniques are activated around some FM frequencies.

Subject: wl12xx: use wiphy values for setting rts, frag thresholds on init

Use the wiphy RTS and fragmentation thresholds for initializing the FW
when possible. This mitigates a bug where previously set values are
forgotten after interface down/up.

Add checks before settings these values to ensure they are valid. Use
default values when invalid thresholds are configured.

Update the default RTS threshold to the maximum value given by the
specification.

Subject: wl12xx: AP-mode - overhaul rate policy configuration

Use the minimal rate configured in the basic rates set as the AP
broadcast and multicast rate. The minimal rate is used to ensure weak
links can still communicate.

When the basic rates contains at least one OFDM rate, configure all
unicast TX rates to OFDM only.

Unify rate configuration on initialization and on change notification
into a single function.
