Well, for a debug hack you can always just add extra clock entries into
some DT node and so avoid clk_get_sys:-)

My point wasn't so much about not using clk_get_sys in a debug driver,
but more that if this patch is only required to support non-upstreamed
debug code, perhaps this patch should stay downstream along with that
non-upstreamed debug code. That said, I'm not really objecting to it,
just making a minor comment.
