drm/msm/dpu: Guard PINGPONG DSC ops behind DPU_PINGPONG_DSC bit
DPU < 7.0.0 has DPU_PINGPONG_DSC feature bit set to indicate it requires
both dpu_hw_pp_setup_dsc() and dpu_hw_pp_dsc_{enable,disable}() to be
executed to complete DSC configuration if DSC hardware block is present.
Hence test DPU_PINGPONG_DSC feature bit and assign DSC related functions
to the ops of PINGPONG block accordingly if DPU_PINGPONG_DSC bit is set.
Changes in v6:
-- split patches, this patch has function handles DPU_PINGPONG_DSC bit
Changes in v9:
-- the original code of assigning dsc related functions to the ops of
pingpong block without testing the DPU_PINGPONG_DSC feature bit was
restored back due to rebase error which defeat the purpose of this
patch. Remove those error code.
Changes in v10:
-- change commit title
-- correct texts at changes in v9
Changes in v12:
-- fixed length too long at Changes in v9
