Add support for the IT8721F/IT8758E. These new chips differ from the
older IT87xxF chips in the following ways:
* ADC LSB is 12 mV instead of 16 mV.
* PWM values are 8-bit instead of 7-bit.
There are other minor changes we don't have to care about in the
driver.

Another change is that we will handle internal voltage scaling in the
driver instead of delegating the work to user-space.

Allow device probing to recognise the Fintek F71808E.

Sysfs interface:
 * Fan/pwm control is the same as for F71889FG
 * Temperature and voltage sensor handling is largely the same as for
   the F71889FG
  - Has one temperature sensor less (doesn't have temp3)
  - Misses one voltage sensor (doesn't have V6, thus in6_input refers to
    what in7_input refers for F71889FG)

For the purpose of the sysfs interface fxxxx_in_temp_attr[] is split up

This patch adds a hwmon driver for package level thermal control. The driver
dumps package level thermal information through sysfs interface so that upper
level application (e.g. lm_sensor) can retrive the information.

Instead of having the package level hwmon code in coretemp, I write a seperate
driver pkgtemp because:

First, package level thermal sensors include not only sensors for each core,
but also sensors for uncore, memory controller or other components in the
package. Logically it will be clear to have a seperate hwmon driver for package
level hwmon to monitor wider range of sensors in a package. Merging package
thermal driver into core thermal driver doesn't make sense and may mislead.

Secondly, merging the two drivers together may cause coding mess. It's easier
to include various package level sensors info if more sensor information is
implemented. Coretemp code needs to consider a lot of legacy machine cases.
Pkgtemp code only considers platform starting from Sandy Bridge.

On a 1Sx4Cx2T Sandy Bridge platform, lm-sensors dumps the pkgtemp and coretemp:

pkgtemp-isa-0000
Adapter: ISA adapter
physical id 0: +33.0°C  (high = +79.0°C, crit = +99.0°C)

coretemp-isa-0000

* Include the right header files
* Clarify why byte swapping of register values is needed
* Strip resolution info bit from temperature register value
* Set cache lifetime to 1/3 second
* Don't arbitrarily reject limit values; clamp as needed

* Properly check for error when setting configuration
* Report error on failed probe
* Make the driver load automatically where needed

Driver for the TI TMP102.

The TI TMP102 is similar to the LM75.  It differs from the LM75 by
having a 16-bit conf register and the temp registers have a minimum
resolution of 12 bits; the extended conf register can select 13-bit
resolution (which this driver does) and also change the update rate
(which this driver currently doesn't use).
