kconfig: Add wildcard support for "source"
Kconfig's include directive "source" does not support
wildcards (e.g. source src/mainboard/*/Kconfig) which
makes automatic inclusion of all boards a tedious task
and prevents us from implementing "drop in" boards.
In our Makefile.inc files we already include mainboard
directories per wildcard, so let's add the infrastructure
to do the same with Kconfig.
