So far we have C preprocessor defines for target and host config options, but we're lacking any information on which devices are available.
We do need that information at times though, for example in the ahci patch where we need to call a legacy init function depending on whether we have support compiled in or not. So this patch makes all config-devices options available as header file. Please only include it in machine description code!
