PFSID should be used in the invalidation descriptor for flushing
device IOTLBs on SRIOV VFs.

When SRIOV VF device IOTLB is invalidated, we need to provide
the PF source ID such that IOMMU hardware can gauge the depth
of invalidation queue which is shared among VFs. This is needed
when device invalidation throttle (DIT) capability is supported.
This patch adds bit definitions for checking
When device invalidation throttling(DIT) is supported by an IOMMU, device TLB
invalidation should include physical function source ID(PFSID).
Changes since v1:
- Fixed compile error when CONFIG_PCI_ATS is not set
- Simplified how PF source ID is retrieved
