iwmc3200wifi: remove driver for unavailable hardware

This hardware never became available to normal humans.  Leaving this
driver imposes unwelcome maintenance costs for no clear benefit.

-	  The Intel Wireless Multicomm 3200 hardware is a combo
-	  card with GPS, Bluetooth, WiMax and 802.11 radios. It
-	  runs over SDIO and is typically found on Moorestown
-	  based platform. This driver takes care of the 802.11

-	  To see the list of debug modules and levels, see iwm/debug.h
-
-	  For example, if you want the full MLME debug output:
-	  echo 0xff > /sys/kernel/debug/iwm/phyN/debug/mlme
-
-	  Or, if you want the full debug, for all modules:
