Some registers for DDI A/B moved to PICA and now follow the same format
as the ones for the PORT_TC ports. The wrapper here deals with 2 issues:
- Share the implementation between xe2lpd and previous
platforms: there are minor layout changes, it's mostly the
register location that changed
- Handle offsets after TC ports
