Staging: remove sxg driver

Unfortunatly, the upstream company has abandonded development of this
driver.  So it's best to just remove the driver from the tree.

-This is the rough cut at a driver for the Alacritech SLIC Technology
-Non-Accelerated 10Gbe network driver.
-
-TODO:
-	- remove wrappers
-	- checkpatch.pl cleanups
-	- new functionality that the card needs
-	- remove reliance on x86
-
-Please send patches to:
-        Greg Kroah-Hartman <gregkh@suse.de>
-for any cleanups that you do to this driver.
