SFI: add sysfs interface for SFI tables.
Analogous to ACPI's /sys/firmware/acpi/tables/...

create /sys/firmware/sfi/tables/

The tables are primariy for the kernel,
but sometimes it is useful for user-space to be
able to read them.

+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
