drm/i915/vdsc: Set VDSC PIC_HEIGHT before using for DP DSC

Browse Source 
Currently, pic_height of vdsc_cfg structure is being used to calculate
slice_height, before it is set for DP.

So taking out the lines to set pic_height from the helper
intel_dp_dsc_compute_params() to individual encoders, and setting
pic_height, before it is used to calculate slice_height for DP.
