This implements the baseline PMU for RISC-V platforms.
To ease future PMU portings, a guide is also written, containing perf concepts, arch porting practices and some hints.
Changes in v2: - Fix the bug reported by Alex, which was caused by not sufficient initialization. Check https://lkml.org/lkml/2018/3/31/251 for the discussion.
