There are currently 3 separate directories for clock debugging in
debugfs: clk_enable, clk_rate, and clk_local. Each of these
directories contains a list of clocks. This is rather annoying
when you are focusing on one clock and want to enable/disable it
and then check its rate. You either have to cd to the other
directory or cat ../clk_rate/<clk>.

Invert the layout so that there is one clock directory containing
a directory for each clock. Inside each respective clock
directory place an enable, rate, and is_local file relating to
the clk_enable, clk_disable, and clk_local directories that exist
today.
