Enable perf tool to exploit POWER 24x7 hardware counters

Parts of the project:
a) Some patches upstream and done
b) Reset targets on remaining features still to be done (jit support, symbol 
names)

Initial patches already accepted by Canonical on 117275. Patchset posted to 
community, waiting on
review. (I had posted a version of the patchset in Dec after fixing minor 
comments. Waiting to hear back from community )

There are two separate patch sets, one for the perf tool and other
for the kernel. They are both available in mainline 3.19-rc4.

powerpc/perf/hv-24x7: Document sysfs event description entries

Never mind.

'git describe' seems to think they are in 3.19-rcX but they are
not in 3.19.

$ git describe fd979c0
v3.19-rc2-62-gfd979c0

$ git describe aaea361
v3.19-rc4-172-gaaea361

They were merged on Feb 2, so they should be in 4.0

  Never mind.

  'git describe' seems to think they are in 3.19-rcX but they are
  not in 3.19.

  $ git describe fd979c0
  v3.19-rc2-62-gfd979c0

  $ git describe aaea361
  v3.19-rc4-172-gaaea361

  They were merged on Feb 2, so they should be in 4.0
