[PATCH 0/8] iommu: Make core iommu-groups code more generic

Hi,

this patch-set makes the core code for managing iommu-groups
more generic by lifting its dependencies on PCI. The core
function iommu_group_get_for_dev() had a hard dev_is_pci()
check in it, followed by PCI specific handling.

This check is removed in favour of the the revived
device_group() iommu-ops call-back. With this call-back an
IOMMU driver can define how the devices it manages are
grouped together. Two functions, one generic and one for PCI
devices, are provided that can be uses as a device_group()
call-back or might be used in such a call-back.

The existing drivers making use of the iommu_group_get_for_dev()
function are converted to this call-back.
