Add preprocessor macros for the important PRCI output clocks
that are needed by both the FU540 PRCI driver and DT data.
Details are available in the FU540 manual in Chapter 7 of

Rob, Mark: this patch is a prerequisite for both the FU540 DT data
and for the FU540 PRCI clock driver patch series.  To prevent one
of those patch series from depending on the other, I'd like to ask
Palmer to merge this patch in one of his -rc pull requests.  Could
I get an ack from one or both of you for this purpose?  Thanks.
