It should actually be:

parent_names[0] = avpllb_names[CH4];
parent_names[1] = avpllb_names[CH5];
parent_names[2] = avpllb_names[CH6];
parent_names[3] = avpllb_names[CH7];
parent_names[4] = refclk_names[SYSPLL];

The only valid choice here should be (remember, we are not adding 1 to
the index anymore):
parent_names[4] = refclk_names[MEMPLL];

This is where it gets tricky, now we should have:
parent_names[0] = avpllb_names[CH4];
parent_names[1] = avplla_names[CH5];
parent_names[2] = avpllb_names[CH6];
parent_names[3] = avpllb_names[CH7];
parent_names[4] = refclk_names[SYSPLL];
