sfi: Remove framework for deprecated firmware 



SFI-based platforms are gone. So does this framework.

This removes mention of SFI through the drivers and other code as well.

Date:		May 2010

Contact:	Len Brown <lenb@kernel.org>

Description:

		SFI defines a number of small static memory tables

		so the kernel can get platform information from firmware.



		The tables are defined in the latest SFI specification:

		http://simplefirmware.org/documentation



		While the tables are used by the kernel, user-space

		can observe them this way::



		  # cd /sys/firmware/sfi/tables

		  # cat $TABLENAME > $TABLENAME.bin
