Add "enable state" column to the clk summary. It's handy to know actual hardware state of all clocks for debugging purposes. In conjunction with clk_ignore_unused, this tells us what unused clocks are left on after bootloader without disabling the clocks. It's also s useful debugging information for cases where firmware touches clocks.
