Merge branches 'acpi-pm' and 'acpi-x86'

Merge additional ACPI quirks for x86 systems:

 - Drop a suspend-to-idle quirk for HP Elitebook G9 that is not needed
   any more after a firmware update (Mario Limonciello).

 - Add all Cezanne systems to the list for forcing StorageD3Enable,
   because they all need the same quirk (Mario Limonciello).

* acpi-pm:
  ACPI: x86: Drop quirk for HP Elitebook

* acpi-x86:
  ACPI: x86: utils: Add Cezanne to the list for forcing StorageD3Enable
