selftests/powerpc: Add test for VPHN The goal is to verify vphn_unpack_associativity() parses VPHN numbers correctly. We feed it with a variety of input values and compare with expected results. PAPR+ does not say much about VPHN parsing: I came up with a list of tests that check many simple cases and some corner ones. I wouldn't dare to say the list is exhaustive though.
