Arnaldo Carvalho de Melo dd678532f9 perf header: Additional note on AMD IBS for max_precise pmu cap 
x86 core PMU exposes supported maximum precision level via max_precise
PMU capability. Although, AMD core PMU does not support precise mode,
certain core PMU events with precise_ip > 0 are allowed and forwarded to
IBS OP PMU.

Display a note about this in the 'perf report' header output and
document the details in the perf-list man page.
