hwmon: Remove pkgtemp driver
After the merge of pkgtemp functionality into the coretemp driver, the pkgtemp driver is no longer necessary. Remove it. Signed-off-by: Guenter Roeck <guenter.roeck@ericsson.com> Cc: Fenghua Yu <fenghua.yu@intel.com> Acked-by: Jean Delvare <khali@linux-fr.org>

-Description
------------
-
-This driver permits reading package level temperature sensor embedded inside
-Intel CPU package. The sensors can be in core, uncore, memory controller, or
-other components in a package. The feature is first implemented in Intel Sandy
-Bridge platform.
-
-Temperature is measured in degrees Celsius and measurement resolution is
-1 degree C. Valid temperatures are from 0 to TjMax degrees C, because the actual
-value of temperature register is in fact a delta from TjMax.
-
-Temperature known as TjMax is the maximum junction temperature of package.
-We get this from MSR_IA32_TEMPERATURE_TARGET. If the MSR is not accessible,
-we define TjMax as 100 degrees Celsius. At this temperature, protection
-mechanism will perform actions to forcibly cool down the package. Alarm
-may be raised, if the temperature grows enough (more than TjMax) to trigger
-the Out-Of-Spec bit. Following table summarizes the exported sysfs files:
-
-temp1_input - Package temperature (in millidegrees Celsius).
-temp1_max - All cooling devices should be turned on.
-temp1_crit - Maximum junction temperature (in millidegrees Celsius).
-temp1_crit_alarm - Set when Out-of-spec bit is set, never clears.
- Correct CPU operation is no longer guaranteed.
