The coretemp driver provides a single set of device attributes for each
physical core of a HT CPU to avoid duplicate sensors.  This
functionality was introduced with commit d883b9f0 ("hwmon:
(coretemp) Skip duplicate CPU entries").

Commit e40cc4bd ("x86/hwmon: register alternate sibling upon CPU
removal") extends this functionality to register the HT sibling of a CPU
which is taken offline, to ensure that sensor attributes are provided if
at least one HT sibling of a core is online.

Add comments into the code describing the functionality in some more
detail.

cpu_sibling_mask() is not defined unless CONFIG_SMP is defined, so it
must not be used directly in the code without ifdef protection.

To solve the problem and avoid ifdefs in the code, define
for_each_sibling() and use it instead.

This patch merges the pkgtemp with coretemp driver.
The sysfs interfaces for all cores in the same pkg
are shown under one directory, in hwmon. It also
supports CONFIG_HOTPLUG_CPU. So, the sysfs interfaces
are created when each core comes online and are
removed when it goes offline.
