selftests/powerpc/pmu: Add support for perf sampling tests
Add support functions for enabling perf sampling test in a new folder
"sampling_tests" under "selftests/powerpc/pmu". This includes support
functions for allocating and processing the mmap buffer. These functions
are added/defined in "sampling_tests/misc.*" files.
Also updates the corresponding Makefiles in "selftests/powerpc" and
"sampling_tests" folder.
