recently as i reviewed the clk-raspberrypi i noticed this, too. But from 
my point of view the clock ids should go to include/dt-bindings/clock 
(like bcm2835.h) because these clock ids are actually referenced in the 
DTS files and we need to make sure they are in sync. AFAIR this would 
also result in change from enum to defines.

Sorry, i didn't had the time to send a patch for this.
