[PATCH v2 0/6] iommu: Pass in old_domain pointer to attach_dev

[Nicolin Chen]

Tidy the release_device callbacks in the drivers and switch to the core
managed release_domain.

This allows the core further to pass in the old domain pointer into the
attach_dev callbacks to reduce the use of iommu_get_domain_for_dev().

This is a preparatory series for new iommu_dev_reset APIs:
