Currently the DRM DSC functions are selected by the
DRM_DISPLAY_DP_HELPER Kconfig symbol. This is not optimal, since the DSI
code (both panel and host drivers) end up selecting the seemingly
irrelevant DP helpers. Split the DSC code to be guarded by the separate
DRM_DISPLAY_DSC_HELPER Kconfig symbol.
