Lu Baolu c714f15860 iommufd: Add fault and response message definitions
iommu_hwpt_pgfaults represent fault messages that the userspace can
retrieve. Multiple iommu_hwpt_pgfaults might be put in an iopf group,
with the IOMMU_PGFAULT_FLAGS_LAST_PAGE flag set only for the last
iommu_hwpt_pgfault.

An iommu_hwpt_page_response is a response message that the userspace
should send to the kernel after finishing handling a group of fault
messages. The @dev_id, @pasid, and @grpid fields in the message
identify an outstanding iopf group for a device. The @cookie field,
which matches the cookie field of the last fault in the group, will
be used by the kernel to look up the pending message.
