s390/cpum_sf: Add raw data sampling to support the diagnostic-sampling function
Also support the diagnostic-sampling function in addition to the basic-sampling function. Diagnostic-sampling data entries contain hardware model specific sampling data and additional programs are required to analyze the data. To deliver diagnostic-sampling, as well, as basis-sampling data entries to user space, introduce support for sampling "raw data". If this particular perf sampling type (PERF_SAMPLE_RAW) is used, sampling data entries are copied to user space. External programs can then analyze these data.
