pvr: emit tpu_tag_cdm_ctrl in compute stream when present

Browse Source 
An extra control register word, tpu_tag_cdm_ctrl, will be present when
TPU_DM_GLOBAL_REGISTERS feature is present.

Emit it when it's needed.

The document of this register is available, however I don't think any of
the bits are needed to be set for our current feature set, so just emit
0 now.
