s390/oprofile: move hwsampler interfaces to cpu_mf.h
Extract and move the oprofile hwsampler data structures and interfaces to
the cpu_mf.h header file which contains common interface definitions
for the various CPU-measurement facilities. This change is necessary for
a new perf PMU.
Few interface names have been revised to fit to the latest CPU-measurement
facilities documentation. Also declare the data structures as __packed and
correct checkpatch findings.
