{nl,cfg}80211: support high bitrates

Browse Source 
Until now, a u16 value was used to represent bitrate value.
With VHT bitrates this becomes too small.

Introduce a new 32-bit bitrate attribute. nl80211 will report
both the new and the old attribute, unless the bitrate doesn't
fit into the old u16 attribute in which case only the new one
will be reported.

User space tools encouraged to prefer the 32-bit attribute, if
available (since it won't be available on older kernels.)
