Pull ACPI fixes from Rafael Wysocki:
 "These update the ACPICA entry in MAINTAINERS, add a backlight handling
  quirk and fix the ACPI PRM (platform runtime) mechanism support.

  Specifics:

   - Update the ACPICA development list address in MAINTAINERS to the
     new one that does not bounce (Rafael Wysocki)

   - Check whether EFI runtime is available when registering the ACPI
     PRM address space handler and when running it (Ard Biesheuvel)

   - Add backlight=native DMI quirk for Acer Aspire 4810T to the ACPI
     video driver (Hans de Goede)"
