[PATCH] ipw2200: print geography code upon module load 

Given the amount of support requests for the meaning of the geography code
I've written a patch for printing this information on module load no matter
the debug level.

I've also added a section to the README.ipw2200 file listing the geography
codes and their meaning.

Upon loading the Intel(R) PRO/Wireless 2915ABG Driver for Linux, a
message stating the detected geography code and the number of 802.11
channels supported by the card will be displayed in the log.
The geography code corresponds to a regulatory domain as shown in the
table below.
