Fix a regression introduced by #21227 0709dc04
(ec/lenovo/h8/acpi/thermal: Add ACPI fan control).
The commit caused Windows to crash as EC reads aren't allowed in the fan
device or it's powerresource's methods. Implement the same approach as all
other platforms using a GNVS variable named FLVL instead of reading from EC.
In addition to EC reads writing to FIELD elements, in another ACPI scope,
seems to be broken. Introduce a new method to set the fan disengage mode.
Tested on Windows 7 and Lenovo T500.

Disengage the fan 10 degree below passive threshold as the automatic EC fan
control does not disengage the FAN even when CPU starts melting ...
* Add EC registers FAND and FANA.
* Add ACPI methods _AC0 and _AL0.
* Add fan device and PowerResource for fan control.
Tested on Lenovo T430:
* The fan disengages at 80°C and keeps running at full speed until temperature
drops below 80°C.
* Fan can be disengaged using sysfs:
/sys/devics/virtual/thermal/cooling_device0/cur_state
Tested on Lenovo T500:
* The fan disengages at 80°C and keeps running at full speed until temperature
drops below 80°C.
* Fan cannot be disengaged using sysfs, but the current state can be read:

The thinkpad-acpi driver uses the UCMS (CMOS) ACPI method to control the
ThinkLight from the Operating System. This patch adds partial support for
that method, enough to enable or disable the ThinkLight:
echo on >/proc/acpi/ibm/light
echo off >/proc/acpi/ibm/light
With the original BIOS the UCMS method exposes a wide range of values
through a generic /proc/acpi/ibm/cmos interface. With the changes suggested
in this patch that interface is also exposed but only accepts the commands
to enable or disable the ThinkLight; all other commands are ignored.
This change would potentially benefit all currently supported Thinkpad
models, I only have an X201 available for tests though.

The Lenovo H8 battery interface uses a paged EC memory area.
Some Thinkpads (in particular the S230U) use a different EC controller
(ENE KB9012) with mostly compatible firmware, which requires an explicit
delay between writing the page register and reading the page data.

Currently, when using `iasl` 20140926-32 [Oct 1 2014] from Debian 8
(Jessie/stable), the build of the Lenovo X60 fails due to syntax errors.
ASL 2.0 supports `<<`. For consistency, right now, coreboot still uses
the old syntax. So use `ShiftLeft` instead, which also fixes the build
issue with older ASL compilers.

thinkpad_acpi expects a SSMS method to turn on/off the mute LED
and a MMTS method to turn on/off the microphone mute LED. With
these methods implemented the driver can correctly sync the LEDs
with the corresponding statuses.
There seems to be two different bits to mute the audio in the
Lenovo H8 EC:
* AMUT, used internally (for example to disable the audio before
entering S3).
* ALMT, controllable by the OS, which also toggles the mute LED
(if present).
Tested on a X220T and on a X201.

On my Thinkpad with an H8-compatible ENE KB9012 EC (GDHT92WW 1.52), when
the battery is nearly full and we switch from battery to AC by plugging
in the cable, the current rate will not drop to 0 immediately, but the
discharging state is cleared immediately.
This leads to the code trying to process an invalid rate value >0x8000,
leading to a displayed rate of >1000W.
This patch changes the logic to deal with these corner cases.

As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.
However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.
util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.
