With the RK3368's limited TPL size, we'll want to use OF_PLATFDATA for
the SPL stage.  This implements support for OF_PLATDATA in the clock
driver for the RK3368.

     TPL or SPL?

Thanks for catching this.

In fact it was first done for SPL and later reused for TPL (when I split the
CONFIG_IS_ENABLED for TPL and SPL). There may be more of such
confused uses of TPL/SPL lurking in my commit messages...
