clk: at91: fix clk_programmable_set_parent()
Since commit 1bdf02326b71e ("clk: at91: make use of syscon/regmap internally"), clk_programmable_set_parent() is always selecting the first parent (AKA slow_clk), no matter what's passed in the 'index' parameter. Fix that by initializing the pckr variable to the index value.
