People testing SPEAr with v3.5-rc1 saw that serial devices don't show

That will still happen with
this patch i believe.

What is expected from Platforms to handle this? AFAICR, we haven't
done anything special
to bind a pinctrl node to a struct dev for uart.

Yeah as Fabio pointed out, activate dummies is the quick
fix.

The "real" fix is to provide atleast a default pin map table
entry (sleep is not needed).

However I think you could benefit from using this on
SPEAr by providing two different pinconf lists for
the default and sleep modes as the ux500 does:
usually this saves some power.
