[PATCH] clk: bcm2835: Fix memory leak in bcm2835_register_pll

[Navid Emamdoost]

In the implementation of bcm2835_register_pll(), the allocated memory
for pll should be released if devm_clk_hw_register() fails.

Fixes: b19f009d4510 ("clk: bcm2835: Migrate to clk_hw based registration and OF APIs")
