selftests/powerpc/pmu: Add selftest for mmcr1 pmcxsel/unit/cache fields

The testcase uses event code "0x21c040" to verify the settings for
different fields in Monitor Mode Control Register 1 (MMCR1). The fields
include PMCxSEL, PMCXCOMB PMCxUNIT, cache. Checks if these fields are
translated correctly via perf interface to MMCR1
