[PATCH][next] clk: bcm2835: fix memork leak on unfree'd pll struct

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The pll struct is being allocated but not kfree'd on an error return
path when devm_clk_hw_register fails.  Fix this with a kfree on pll
if an error occurs.

Addresses-Coverity: ("Resource leak")
Fixes: b19f009d4510 ("clk: bcm2835: Migrate to clk_hw based registration and OF APIs")
