I might be wrong, but I vaguely recall AT91 (?) had this kind of massive
clock tree description in DT and they then switched to much simpler
clock description where the clock topology is encoded in the driver
instead (like what iMX does right now). It might be worth having a look
at that and the reasoning around that conversion.
