drm/msm/dpu: Drop unused qseed_type from catalog dpu_caps

The SSPP scaler subblk is responsible for reporting its version (via the
.id field, feature bits on the parent SSPP block, and since recently
also from reading a register to supersede a read-but-unset version field
in the catalog), leaving this global qseed_type field logically unused.
Remove this dead code to lighten the catalog and bringup-overhead.
