clk: mvebu: fix setting unwanted flags in CP110 gate clock
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.
