Automatic MODULE_ALIAS() for DMI match tables.
This makes modpost handle MODULE_DEVICE_TABLE(dmi, xxxx). I had to change the string pointers in the match table to char arrays, and picked a size of 79 bytes almost at random -- do we need to make it bigger than that? I was a bit concerned about the 'bloat' this introduces into the match tables, but they should all be __initdata so it shouldn't matter too much. (Actually, modpost does go through the relocations and look at most of them; it wouldn't be impossible to make it handle string pointers -- but doesn't seem to be worth the effort, since they're __initdata).
