From: Lucas Stach <dev at lynxeye.de>
The USB clocks are just clock gates, so no need to set a specific clock.
In fact trying to set a specific clock is just a NOP if the requested
clockrate is the same as those of the parent (clk_m) or will trigger a
WARN_ON() if rates don't match up.
As we are not setting a specific rate, nor activating the clocks at
init, there is no point in keeping the the usb entries in the clock init
table.
