Subject: wl12xx: configure rates when working in ibss mode

When working in ibss mode, we don't configure rate policy per station
(as we use the same link for multiple stations), so currently the
1mb/s rate is being used.

Instead, configure the firmware to use the whole 11b rates by default.

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.

From 70f474241b3d5fb633635a2ce39ea9da4afeea6c Mon Sep 17 00:00:00 2001

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.
