Now that domains support being managed by the HW, lets add that
information to the genpd summary.

That's a very personal opinion and take it for what it is, but I think
"_Mode" is excessive given the column is named "mode"

To avoid confusion, would you mind re-phrasing the above to something
along the lines of:

Now that genpd supports dynamically switching the control for an
attached device between hardware- and software-mode,  let's add this
information to the genpd summary in debugfs.
