drm/msm/dpu: Refactor printing of main blocks in device core dump

Currently, the names of main blocks are hardcoded into the
msm_disp_snapshot_add_block function rather than using the name that
already exists in the catalog. Change this to take the name directly from
the catalog instead of hardcoding it.
