tu: Stop setting RB_CCU_DBG_ECO_CNTL to 0 for GMEM passes

Browse source 
I can't find any evidence that the blob ever did this on a740 or a750.
Doing this breaks subsequent sysmem render passes and would force an
otherwise-unnecessary WFI with custom_resolve.

Fixes: 062e90f19b ("freedreno: Move RB_CCU_DBG_ECO_CNTL to raw_magic_regs")
