This describes all of the SCIF hardware of the r8a73a4.
Each node is disabled and may be enabled as necessary

I was just about to add clocks to these devices when I noticed that
these ports are labeled scifb0 to scifb3 in the datasheet. Is there
any deeper reasoning behind this, or did you just forget to reset the
counter after scifa1? :)

Its a while since I wrote this patch.  I think the reason is that I was
blindly following the numbering-scheme used in r8a73a4. In any case, I
think it would be good to name them according to the datasheet.

Could you cook up a patch?
