[v3,05/13] drm/msm/disp/dpu1: Don't use DSC with mode_3d

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()

I think here'd better have WARN_ON(cfg->mode_3d && cfg->dsc) or similar 
dev_warn().

dsc_mask doesn't exist at this point, so the patch should be moved later 
in the series.

You are going to hate me for the comments on this patch. But this chunk 
should also go into dpu_encoder_phys_vid.c, shouldn't it?

Here you are returning the mask, so it should not be bool.

Please ignore this comment, dsc mask already exists.
