brcm80211: cleanup function prototypes
- removed unneeded fn prototypes from include files.
- explicitly marked fn prototypes as extern in include files.
- reordered functions to account for removed forward declarations
in include files.
- removed unused functions: brcms_c_txflowcontrol_override,
brcms_c_txflowcontrol_prio_isset, brcms_c_txflowcontrol.
