clk: mvebu: fix setting unwanted flags in CP110 gate clock
commit ad715b268a501533ecb2e891a624841d1bb5137c upstream. Armada CP110 system controller comprises its own routine responsble for registering gate clocks. Among others 'flags' field in struct clk_init_data was not set, using a random values, which may cause an unpredicted behavior. This patch fixes the problem by resetting all fields of clk_init_data before assigning values for all gated clocks of Armada 7k/8k SoCs family. Fixes: d3da3eaef7f4 ("clk: mvebu: new driver for Armada CP110 system ...")
