The CPU PMU name depends on the system: armv8_pmuv3_0 is what ACPI
systems get, while on devicetree systems it comes from the compatible
string, e.g. armv8_pmuv3 or armv8_cortex_a76. Maybe add a sentence
after the example, along the lines of:

  The CPU PMU name depends on the system; the available PMUs are
  listed under /sys/bus/event_source/devices/.

I applied the documentation hunks and built htmldocs, no new warnings.
