 - Fix evaluating the _PDC ACPI control method when running as Xen
   dom0 (Roger Pau Monne).

 - Use platform devices to load ACPI PPC and PCC drivers (Petr Pavlu).

 - Check for null return of devm_kzalloc() in fch_misc_setup() (Kang
   Chen).

 - Log a message if enable_irq_wake() fails for the ACPI SCI (Simon
   Gaiser).

 - Initialize the correct IOMMU fwspec while parsing ACPI VIOT
   (Jean-Philippe Brucker).
