Nak. clk_summary is about taking a snapshot of the system state
for things that may be changing rapidly, like consumers (which
sounds fun to add!), rates, enable/prepare state. Flags are not
changing. If you want to add flag info into some summary then a
script should be able to augment clk_summary info (really should
use the clk_dump in this case though) with whatever flags can be
read through debugfs already.
