clk: at91: fix clk_programmable_set_parent()

Browse Source 
Since commit 1bdf02326b ("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.
