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. Signed-off-by: Feng Tang <feng.tang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

+What: /sys/firmware/sfi/tables/
+Date: May 2010

+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
