708597daf2 powerpc/perf: init pmu from core-book3s 
Currenty pmu driver file for each ppc64 generation processor
has a __init call in itself. Refactor the code by moving the
__init call to core-books.c. This also clean's up compat mode
pmu driver registration.

8abd818fc7 powerpc/perf: Pass the struct perf_events down to compute_mmcr() 
To support per-event exclude settings on Power8 we need access to the
struct perf_events in compute_mmcr().

f2699491e0 powerpc/perf: Move perf core & PMU code into a subdirectory 
The perf code has grown a lot since it started, and is big enough to
warrant its own subdirectory. For reference it's ~60% bigger than the
oprofile code. It declutters the kernel directory, makes it simpler to
grep for "just perf stuff", and allows us to shorten some filenames.

While we're at it, make it more obvious that we have two implementations
of the core perf logic. One for (roughly) Book3S CPUs, which was the
original implementation, and the other for Freescale embedded CPUs.
