The call to dm646x_init() is dropped here, but I don't see it added
back, at least in this patch.

I think we should leave the DM646x case out of this since there are
additional issues like introducing these EVM specific defines in a file
meant for SoC.

Is this clean-up a must for you to implement rest of the series (haven't
looked at other patches yet).
