drm/display: Move DSC header and helpers into display-helper module

2022-04-25T09:19:36Z

DSC is the Display Stream Compression standard for DisplayPort. Move the DSC code into display/ and split the header into files for protocol core and DRM helpers. Adapt all users of the code. No functional changes. To avoid the proliferation of Kconfig options, DSC is part of DRM's support for DisplayPort. If necessary, a new option could make DSC an independent feature.

drm/amd/display: move FPU associated DSC code to DML folder

2021-10-28T18:26:14Z

[Why & How] As part of the FPU isolation work documented in https://patchwork.freedesktop.org/series/93042/, isolate code that uses FPU in DSC to DML, where all FPU code should locate. This change does not refactor any functions but move code around.
