drm/msm/dpu: Tear down DSC datapath on encoder cleanup

Unset DSC_ACTIVE bit at dpu_hw_ctl_reset_intf_cfg_v1(),
dpu_encoder_unprep_dsc() and dpu_encoder_dsc_pipe_clr() functions
to tear down DSC data path if DSC data path was setup previous.

Changes in V10:
-- pass ctl directly instead of dpu_enc to dsc_pipe_cfg()
-- move both dpu_encoder_unprep_dsc() and dpu_encoder_dsc_pipe_clr() to above phys_cleanup()
