At legacy chipsets, it required DPU_PINGPONG_DSC bit be set to indicate
pingpong ops functions are required to complete DSC data path setup if
this chipset has DSC hardware block presented. This patch add
DPU_PINGPONG_DSC bit to both PP_BLK and PP_BLK_TE marcos if it has DSC
hardware block presented.

Just to doublecheck: why don't we have DPU_PINGPONG_DSC for PP_3/_4? 
We do have them on sdm845. Is it because we should not use DSC with 
thos PINGPONG blocks?

I think it only have two DSPP connect to pp blocks

[skipped the rest, looks good to me]
