iommu/vt-d: Separate page request queue from SVM

Browse source

[ Upstream commit 4d54409576 ]

IO page faults are no longer dependent on CONFIG_INTEL_IOMMU_SVM. Move
all Page Request Queue (PRQ) functions that handle prq events to a new
file in drivers/iommu/intel/prq.c. The page_req_des struct is now
declared in drivers/iommu/intel/prq.c.

No functional changes are intended. This is a preparation patch to
enable the use of IO page faults outside the SVM/PASID use cases.
