perf/x86/intel/uncore: Fix the scale of IIO free running counters on SPR
The scale of IIO bandwidth in free running counters is inherited from
the ICX. The counter increments for every 32 bytes rather than 4 bytes.
The IIO bandwidth out free running counters don't increment with a
consistent size. The increment depends on the requested size. It's
impossible to find a fixed increment. Remove it from the event_descs.
