perf/x86/intel/uncore: Fix the scale of IIO free running counters on ICX
There was a mistake in the ICX uncore spec too. The counter increments
for every 32 bytes rather than 4 bytes.
The same as SNR, there are 1 ioclk and 8 IIO bandwidth in free running
counters. Reuse the snr_uncore_iio_freerunning_events().
Fixes: 2b3b76b5ec67 ("perf/x86/intel/uncore: Add Ice Lake server uncore support")
