[PATCH 0/9] drm/amd/display: convert GPIO translation logic to lookup tables

[Guilherme Ivo Bozi <guilherme.bozi@usp.br>]

This series converts the GPIO HW translation logic used by
multiple DCN generations from large switch statements to
static lookup tables with shared helper functions.

The new implementation reduces duplicated translation logic
across generations and makes the GPIO mappings easier to
maintain and extend.

The series introduces generic GPIO translation helpers first,
followed by per-generation conversions.

The following generations were converted:

  - dcn10
  - dcn20
  - dcn21
  - dcn30
  - dcn315
  - dcn32
  - dcn401
  - dcn42

The dce60, dce80, dce110 and dce120 implementations were
left unchanged for now.

dce60 and dce80 contain special switch-case handling paths
that currently do not map cleanly to the new table-based
representation, so they were intentionally excluded from
this refactor.

No functional changes intended.
