Clock lookups that only involve a hardware clock name, with no device, 
should be the province of the clock code itself, not clkdev.  The clkdev 
code may handle this today in the OMAP code, but this is simply due to 
legacy reasons.

In general, on OMAP, we've got much faster ways now to implement 
clk_get().
