Subject: clk: at91: fix clk_programmable_set_parent()

From: Boris Brezillon <boris.brezillon@free-electrons.com>

commit f96423f483b1a7854270335b319e8d1cdd6f3585 upstream.

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.
