drm/i915/dp: Fix DSC enable code to use cpu_transcoder instead of encoder->type
This patch fixes the intel_configure_pps_for_dsc_encoder() function to use
cpu_transcoder instead of encoder->type to select the correct DSC registers
that was wrongly used in the original patch for one DSC register isntance.
Fixes: 7182414e2530 ("drm/i915/dp: Configure i915 Picture parameter Set registers during DSC enabling")
