We cannot enable mode_3d when we are using the DSC. So pass configuration to detect DSC is enabled and not enable mode_3d when we are using DSC
We add a helper dpu_encoder_helper_get_dsc() to detect dsc enabled and pass this to .setup_intf_cfg()

I'd prefer if we disable mode_3d here, rather than ignoring it in the dpu_hw_ctl_intf_cfg()
