[00/19] Consolidation of DSS Control in Separate Files

Message

Nautiyal, Ankit K Aug. 30, 2024, 5:09 a.m. UTC

Currently, DSS control is configured from various files; this change aims
to consolidate all DSS-related functionalities, such as display stream
splitting, joining, MSO configuration, and joining configuration,
into one place.

A new file, intel_dss_regs.h, will store register information, while the
helpers to configure DSS and related stuff will be moved to intel_dss.c
with its corresponding header file intel_dss.h.
Along with this, the helpers related to retrieve information about the
pipe joiners are also moved from intel_display.c to intel_joiner.

Additionally, wherever possible, the drm_i915_private structure is
replaced with the new intel_display structure as part of ongoing efforts
to phase out the old structure.

Rev2:
-Addressed review comments from Jani.
-Moved all joiner stuff into a separate file.

Rev3:
-Rebase
