This is a new driver for the SMSC EMC6W201 hardware monitoring device.
The device is functionally close to the EMC6D100 series, but is
register-incompatible.

The abituguru drivers are only built on X86, where DMI support is now
enabled by default. So let these drivers depend on DMI, for the
following gains:
* Robustness and safety. Detection of these devices is weak and uses
  non-standard methods, it should really be limited to Abit boards
  unless the user explicitly asks otherwise.
* Code simplicity. The code is easier to read without ifdefs.
* Better build testing coverage. Now there's only one way to build the
  drivers, so no risk of build failure on exotic systems.

Serialize access to the hardware by using "request_muxed_region" macro
defined by Alan Cox. Call to this macro will hold off the requestor if
the resource is currently busy. "superio_enter" will return an error
if call to "request_muxed_region" fails. Rest of the code change is to
ripple an error return from superio_enter to the top level.

As discussed earlier, the ACPI power meter driver would better live
in drivers/hwmon, as its only purpose is to create hwmon-style
interfaces for ACPI 4.0 power meter devices. Users are more likely to
look for it there, and less likely to accidentally hide it by
unselecting its dependencies.

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
