    clk: visconti: Fix memory leak in visconti_register_pll()
    
    [ Upstream commit b55226f8553d255f5002c751c7c6ba9291f34bf2 ]
    
    @pll->rate_table has allocated memory by kmemdup(), if clk_hw_register()
    fails, it should be freed, otherwise it will cause memory leak issue,
    this patch fixes it.
