drm/i915/xe2lpd: Move registers to PICA
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
v2:
- Explain better the trick to use just the second range (Matt Roper)
- Add missing conversions after rebase (Matt Roper)
- Use macro instead of inline function, avoiding includes in the
header (Jani)
- Prefix old macros with underscore so they don't get used by mistake,
and name the new ones using the previous names
v3: Use the same logic for the recently-introduced XELPDP_PORT_MSGBUS_TIMER
(Gustavo)
