The DSI pixel clocks are muxed from clocks generated in the analog phy
by the DSI driver. In order to set them as parents, we need to do the
same name lookup dance on them as we do for our root oscillator.

This proved incredibly useful during debugging of the DSI driver, to
see if our clocks were running at rate we requested. Let's leave it
here for the next person interacting with clocks on the platform (and
so that hopefully we can just hook it up to debugfs some day).
