selftests/powerpc/pmu/: Add interface test for mmcr0_fc56 field using pmc1
The testcase uses event code 0x1001e to verify two bit settings (FC5-6
and PMC1CE) in Monitor Mode Control Register 0 (MMCR0). Check if FC5-6
bit to be set in MMCR0 when not using Performance Monitor Counter 5 and
6 (PMC5 and PMC6). And also PMC1CE is expected to be set when using
PMC1. Test if these fields are programmed correctly via perf interface.
