So we update the rules by default for AP. Then in next patch 5/12, once 
STA connects to AP, we put the proper power mode and refresh the rules.

So if user wants to bring up 1 STA interface alone, in total 3 
regulatory updates will happen from driver to upper layer -
1. During initial boot time
2. During interface create time (above hunk)
3. During channel context assignment (5/12 patch)

Does this seem good? 3 times we would be changing regulatory rules and 
first 2 times we are doing the same thing.
