The DPU_PINGPONG_TE bit is set for all PINGPONG blocks on DPU < 5.0.
Rather than checking for the flag, check for the presense of the
corresponding interrupt line.

In hindsight, maybe there's one patch missing from this series. You
inlined _setup_intf_ops() later, but there's no patch inlining
_setup_pingpong_ops() which looks to be required for applying this
patch.
Yes, I missed it somehow.
