platform/x86: thinkpad_acpi: Add Thinkpad Edge E531 fan support

Browse source

Fan control on the E531 is done using the ACPI methods FANG and
FANW. The correct parameters and register values were found by
analyzing EC firmware as well as DSDT. This has been tested on
my Thinkpad Edge E531 (6885CTO, BIOS HEET52WW 1.33).
