Freerunning counter events are repetitive: the event code is fixed to
0xff, the unit is always "MiB", and the scale is identical across all
counters on a given PMON unit.

Introduce a new helper macro, INTEL_UNCORE_FR_EVENT_DESC(), to populate
the event, scale, and unit descriptor triplet. This reduces duplicated
lines and improves readability.

No functional change intended.
