drm/i915/dp: Check for HAS_DSC_3ENGINES while configuring DSC slices
DSC 12 slices configuration is used for some specific cases with
Ultrajoiner. This can be supported only when each of the 4 joined pipes
have 3 DSC engines each.
Add the missing check for 3 DSC engines support before using 3 DSC
slices per pipe.
Fixes: be7f5fcdf4a0 ("drm/i915/dp: Enable 3 DSC engines for 12 slices")
