Sync wpa_supplicant man page with README changes

The man page source was not up-to-date with removed driver wrappers,
so bring in the wpa_supplicant/README changes to make this somewhat
closer to the current state.

-	not publicly available except for couple of exceptions, mainly
-	Broadcom-based APs/wireless routers that use Linux. The driver
-	binary can be downloaded, e.g., from Linksys support site
-	(http://www.linksys.com/support/gpl.asp) for Linksys
-	WRT54G. The GPL tarball includes cross-compiler and the needed
-	header file, wlioctl.h, for compiling wpa_supplicant.  This
-	driver support in wpa_supplicant is expected to work also with
-	other devices based on Broadcom driver (assuming the driver
-	includes client mode support).</para>
