iwlwifi: split the drivers for agn and legacy devices 3945/4965

Intel WiFi devices 3945 and 4965 now have their own driver in the folder

	drivers/net/wireless/iwlegacy

Add support to build these drivers independently of the driver for
AGN devices. Selecting the 3945 builds iwl3945.ko and iwl_legacy.ko,
and selecting the 4965 builds iwl4965.ko and iwl_legacy.ko. iwl-legacy.ko
contains code shared between both devices.

The 3945 is an ABG/BG device, with no support for 802.11n. The 4965 is a 2x3
ABGN device.

+          This driver uses the kernel's mac80211 subsystem.
+
+          In order to use this driver, you will need a microcode (uCode)
+          image for it. You can obtain the microcode from:
+
+                  <http://intellinuxwireless.org/>.
+
+          The microcode is typically installed in /lib/firmware. You can
+          look in the hotplug script /etc/hotplug/firmware.agent to
+          determine which directory FIRMWARE_DIR is set to when the script
+          runs.
+
+          If you want to compile the driver as a module ( = code which can be
+          inserted in and removed from the running kernel whenever you want),
+          say M here and read <file:Documentation/kbuild/modules.txt>.  The
+          module will be called iwlagn.
