[reggen] Replace prim_pulse_sync with prim_sync_reqack

- This was an oversight, the CDC handling inside reg_top
  used to use prim_pulse_sync. This worked fine if the
  source clock is much slower than the destination clock,
  but cannot always assumed to be true.

- Switch to prim_sync_reqack which has more robust handling
  of clock ratios and is tolerant to a source faster than
  the destination.
