iommu/vt-d: Add helper to setup pasid nested translation
The configurations are passed in from the user when the user domain is
allocated. This helper interprets these configurations according to the
data structure defined in uapi/linux/iommufd.h. The EINVAL error will be
returned if any of configurations are not compatible with the hardware
capabilities. The caller can retry with another compatible user domain.
The encoding of fields of each pasid entry is defined in section 9.6 of
the VT-d spec.
