Re: [PATCH 10/18] iommu/fsl_pamu: enable the liodn when attaching a device

Instead of a separate call to enable all devices from the list, just enablde the liodn one the device is attached to the iommu domain.

(typos: "enablde" and "one" probably needs to be "once"?)

This also remove the DOMAIN_ATTR_FSL_PAMU_ENABLE iommu_attr.
