OK.  The hwmod optional clocks weren't intended to map directly to the 
OMAP4 notion of optional clocks.  But sounds like this would require a bit 
more thought.  So let's go with your original patch.  Will ack it after 
sending this.

It works via clk_get(), so using the hwmod optional clocks would require 
no driver changes.
