Some chips can read external temperature sensor values only to TMPIN3.
These use EC register 0x55, bit 7 to enable that. This patch adds
support for this. It is called "old PECI" by lm_sensors [0].
Other chips can read to any TMPIN[1-3] which is configured in EC
register 0x51 like the other temperature sources. This was the only
supported method. This patch adds a Kconfig option to indicate this
variant.
This patch was tested on an Acer Aspire M3800 which has an IT8720F that
reads the CPU temperature via PECI. It allows the automatic fan control
feature of the Super I/O to work.
Overview of support per chip in the coreboot tree, determined from
reading the publicly available datasheets or lm_sensors, if noted:
Old PECI:
* IT8718F
* IT8720F
* IT8781F, IT8782F, IT8783E/F
Normal PECI:
* IT8721F (exception: no PECI to TMPIN2)
* IT8728F
* IT8772E (uses separate code in coreboot, not superio/ite/common)
* IT8786E
* IT8613E, IT8623E (lm_sensors)

The interface selection register of the environment controller (EC)
gives the choice between "Internal generated 32 MHz" and "24 MHz" for
the "SST/PECI Host Controller Clock Selection".
Previously the chip was always configured for the 32 MHz clock. Add an
option that can be set from devicetree.cb to allow using the 24 MHz
clock.
Without this setting the automatic fan control on an Acer Aspire M3800
was slow to respond to temperature changes.

This applies to the automatic fan control mode of the environment
controller (EC). Previously the affected bit was always cleared while
the default value is 1 according to datasheets. Add a variable that can
be set per mainboard in devicetree.cb.
In the IT8783E datasheet that bit is marked as reserved.

access their hardware monitor/environment controller in the SIO chip, so
move this to a common location and replace the inb/outb calls with the
corresponding inline functions from device/pnp.h

Some ITEs have more than 3 independent FAN controller outputs. As the
initial implementation assumed only 3 outputs some registers are not
consequently numbered. This change adds macros for accessing those
registers.
Additionally some chips have SmartGuardian always enabled, without the
option for turning it off. For these chips bits that were responsible
for ON/OFF control are either reserved or have different meaning.
Another Kconfig option is added to disable ON/OFF functionality on
platforms that do not support it.

Instead of setting "peci_tmpin" in the devicetree, THERMAL_PECI is now
a mode of TMPIN like THERMAL_RESISTOR and THERMAL_DIODE. Since the logic
to set temperature offsets and limits is in the function that sets
thermal modes, it makes sense to treat PECI as yet another mode.
As of this commit, there are no boards that actually use peci_tmpin from
ite/common. There are three boards that have a similar device tree
option, but those boards use it8772f, which implements all superio
functions on its own.
The first user will probably be Gigabyte GA-Z77-DS3H.

Add devicetree options to set temperature limits that are used to alarm
user when temperature exceeds defined values.
Audio alerts by superio are not implemented yet, but since limits are
visible to userland, some software might use them as is. For instance,
lm-sensors displays "ALERT" when temperature exceeds limits.

Add a devicetree option to set temperature adjustment registers
required for thermal diode sensors and PECI. However, this commit does
not have the code needed to make PECI interface actually use these
registers. It only applies to diodes.
As a temporary workaround, one can set both THERMAL_DIODE and peci_tmpin
to the same TMPIN, e.g. TMPIN3.mode="THERMAL_DIODE" and peci_tmpin="3".
PECI, apparently, takes precedence over diode, so the adjustment register
will be set and PECI activated. Or simply use the followup patch, which
makes THERMAL_PECI a mode like THERMAL_DIODE.
I don't have hardware to test THERMAL_DIODE mode, but in case of PECI,
without this patch I had about -60°C on idle. Now, with offset 97,
which was taken from vendor bios, PECI readings became reasonable 35°C.
TEST=Set a temperature offset, then ensure that the value you set is
reflected in /sys/class/hwmon/hwmon*/temp[1-3]_offset

The environment-controller entity is shared by many ITE super-i/o
chips. There are some differences between the chips, though. To cover
that, the super-i/o chip should select Kconfig options of this driver
accordingly.
The current implementation isn't exhaustive: It covers only those
parts that are connected on boards I could test, plus those that are
currently used by the IT8772F. The latter could be ported to use this
driver if somebody minds to test it.
