[PATCH v12 04/21] clk: Fix clk_get_by_* handling of index

clk_get_by_index_nodev only ever fetched clock 1, due to passing a boolean
predicate instead of the index. Other clk_get_by_* functions got the clock
correctly, but passed a predicate instead of the index to clk_get_by_tail.
This could lead to confusing error messages.
