ACPI and power management fixes for 3.12-rc5

 - The WARN_ON() in acpiphp_enumerate_slots() triggers as a false
   positive in some cases, so drop it.

 - Add a missing pci_dev_put() to an error code path in
   acpiphp_enumerate_slots().

 - Replace my old e-mail address that's going to expire with a new one.

 - Update ACPI web links and git tree information in MAINTAINERS.

 - Update links to the Linux-ACPI project's page in MAINTAINERS.

 - Update some stale links and e-mail addresses under Documentation
   and in the ACPI Kconfig file.
