PATCH v6 4/5 pci/layerscape: add defines for LUT

From: Stuart Yoder <[email protected]>

The per-PCI controller LUT (Look-Up-Table) is a 32-entry table that maps PCI requester IDs (bus/dev/fun) to a stream ID.

Add defines for the register offsets.

Applied to u-boot-fsl-qoriq, awaiting upstream.

Thanks.
