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.

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
