selftests/powerpc/pmu/: Add interface test for mmcr0_pmc56 using pmc5

Browse Source 
The testcase uses event code 0x500fa to verify the FC5-6 bit setting in
Monitor Mode Control Register 0 (MMCR0). Check if FC5-6 bit is not set
in MMCR0 when using Performance Monitor Counter 5 and 6 (PMC5 and PMC6).
