When radar is found in any DFS channel, a radar bitmap is
generated based on the radar infected channels. For example,
if operating channel is 100 HT160 and radar found in 112,
then the generated bitmap is B0000_0010. This proposed bitmap
is compared with the valid puncturing patterns. In this case,
the proposed bitmap is valid puncturing pattern.
In case of a valid puncturing pattern, send the final
bitmap to DFS module and the module updates the DFS channel
puncturing pattern. If an invalid puncturing pattern is
found, return value zero and do not update DFS channel
puncturing pattern.
