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.
