Add defconfigs for both 32- and 64-bit machines. We could in theory drop the mach directory altogether like it's done on arm64, but for now it's left in as it provides . It's expected that we can drop it in future in favor of generic earlycon support (which also wouldn't require manual adjustment of the shared entry point like with debug_ll).
