perf cpuid: Introduce a platform specific cpuid compare function
The function get_cpuid_str() is called by perf_pmu__getcpuid() and on
s390 returns a complete description of the CPU and its capabilities,
which is a comma separated list.
To map the CPU type with the value defined in the
pmu-events/arch/s390/mapfile.csv, introduce an architecture specific
cpuid compare function named strcmp_cpuid_str()
The currently used regex algorithm is defined as the weak default and
will be used if no platform specific one is defined. This matches the
current behavior.
