[PATCH] clk: sprd: add missing kfree

[Chunyan Zhang]

From: Chunyan Zhang <chunyan.zh...@unisoc.com>

The number of config registers for different pll clocks probably are not
same, so we have to use malloc, and should free the memory before return.

Fixes: 3e37b005580b ("clk: sprd: add adjustable pll support")
