Rajkumar Manoharan c3701c66a5 Add handling of OBSS scan requests and 20/40 BSS coex reports
Add support for HT STA to report 40 MHz intolerance to the associated AP.
A HT station generates a report (20/40 BSS coexistence) of channel list
if it finds a non-HT capable AP or a HT AP which prohibits 40 MHz
transmission (i.e., 40 MHz intolerant bit is set in HT capabilities IE)
from the scan results.

Parse the OBSS scan parameter from Beacon or Probe Response frames and
schedule periodic scan to generate 20/40 coexistence channel report if
requested to do so. This patch decodes Scan Interval alone from the OBSS
Scan Parameters element and triggers scan on timeout.
