Subject: clk: sprd: add missing kfree
Git-commit: 5e75ea9c67433a065b0e8595ad3c91c7c0ca0d2d
Patch-mainline: 5.4-rc1
References: bnc#1151927 5.3.5

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")
