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 v5:
 - Fix patch errors from checkpatch.pl.

Changes in v4:
 - Fix several compilation errors.  Sorry for that.
 - Raise a warning in the write_counter body.

Changes in v3:
 - Fix typos in the document.
 - Change the initialization routine from statically assigning PMU to
   device-tree-based methods, and set default to the PMU proposed in
   this patch.

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.
