selftests/powerpc/pmu: Add interface test for mmcra register fields

Browse source

The testcase uses event code 0x35340401e0 to verify the settings for
different fields in Monitor Mode Control Register A (MMCRA). The fields
include thresh_start, thresh_stop thresh_select, sdar mode, sample and
marked bit. Checks if these fields are translated correctly via perf
interface to MMCRA.
