IMHO having 2 different ways to enable the clocks in SPL and in u-boot 
is an not improvement over the current situation.
In any case, This is a subject that can be discussed.

Tom, Lokesh,  do you have an opinion on this ?

Meanwhile It would nice to have DM_USB support for the DRA7/AM57 
platforms. It allows using a USB ether adapter with CONFIG_DM_ETHER 
enabled (default on TI's platform). And this series allows using the USB 
3.0 on AM57 evm.
