If the drivers want to use it, I think it has to be orion_find_tclk for
drivers that are shared between multiple plat-orion platforms.

IMHO it's best to leave any such hacks out of the device tree for
now, until we have the proper clk bindings in place for kirkwood,
and then we can just use those.
