The existing logic removes the passive scan flag from
channels 12 and 13 when a regulatory hint coming from
something other than a country IE has been passed. This
is incorrect, the original intention was to ensure we
always have passive scan enabled for these two channels
for a specific set of custom world regulatory domains.

There is no code in brcmsmac that uses a function from CRC8 or
