This is always 0, 1.

And then this is not really doing much. So I wonder why we really
even need a parent_map? More like we need a map from parent_names
to mux number. We don't need to map some random enum into another
number space like we do for RCGs. I think we may have the same
problem with another qcom clk patch (see commit df964016490b in
clk-next). We really don't need the rcg version of parent_map in
either case, more like we just need a u8 *table (or u32
whatever), and then we're done. I'm going to make that change now
because otherwise we get into a mess with the parent_map stuff in
the other branch. I'll go clean up that too so we don't move
parent_map around.
