iommu: Add mm_get_enqcmd_pasid() helper function
[ Upstream commit 2396046d75d3c0b2cfead852a77efd023f8539dc ]
mm_get_enqcmd_pasid() should be used by architecture code and closely
related to learn the PASID value that the x86 ENQCMD operation should
use for the mm.
For the moment SMMUv3 uses this without any connection to ENQCMD, it
will be cleaned up similar to how the prior patch made VT-d use the
PASID argument of set_dev_pasid().
The motivation is to replace mm->pasid with an iommu private data
structure that is introduced in a later patch.
