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.
