oprofile: Abstract the perf-events backend
Move the perf-events backend from arch/arm/oprofile into
drivers/oprofile so that the code can be shared between architectures.
This allows each architecture to maintain only a single copy of the PMU
accessor functions instead of one for both perf and OProfile. It also
becomes possible for other architectures to delete much of their
OProfile code in favour of the common code now available in
drivers/oprofile/oprofile_perf.c.
