selftests/powerpc/pmu: Add selftest for group constraint check for MMCRA thresh_ctl field
Thresh control bits in the event code is used to program thresh_ctl
field in Monitor Mode Control Register A (MMCRA: 48-55). When scheduling
events as a group, all events in that group should match value in these
bits. Otherwise event open for the sibling events will fail.
Testcase uses event code PM_MRK_INST_CMPL (0x401e0) as leader and
another event PM_THRESH_MET (101ec) as sibling event, and checks if
group constraint checks for thresh_ctl field added correctly via perf
interface.
