clk: ingenic: Allow specifying common clock flags
Provide a flags field for clocks under the ingenic-cgu driver, which can be used to set generic common clock framework flags on the created clocks. For example, the CLK_IS_CRITICAL flag is needed for some clocks (such as CPU or memory) to stop them being automatically disabled.
