disp: msm: sde: detach dsc/vdc encoder blocks properly during modeswitch

Browse Source 
In the current code if there is a switch from DSC to non-DSC
mode, all the DSC blocks attached to the sde_encoder are not
cleaned up properly. Due to this, during virt disable these
DSC blocks are disabled and flushed resulting in underruns
on other ctl paths which might be using them. This change
properly cleans up all the dsc/vdc attached to the sde
encoder to avoid such issues.
