It might be worth repeating that the problem that needs to be solved is
that we have an IP block that exists in some sense but needs to be shut
down (or some similar case the driver can handle) rather than ignored
like today.  This is not the same as having 5 UARTs available from the
SoC but only one is actually in some useful physical state, so list all
5 in the dtsi, status disabled, and then in the board dts file enable
the exposed ones.
