Introduce INTEL_DISPLAY_DEVICE_*_OFFSET() macros to compute absolute MMIO offsets for pipe, transcoder, and cursor registers. Update _MMIO_PIPE2/_MMIO_TRANS2/_MMIO_CURSOR2 to use these macros for cleaner abstraction and to prepare for external API usage (e.g. GVT). Also move DISPLAY_MMIO_BASE() to intel_display_device.h so it can be abstracted in GVT, allowing register macros to resolve via exported helpers rather than peeking into struct intel_display. v2: Wrap the macro argument usages in parenthesis.
