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.
