boards: add a 'none' machine type to all platforms
This allows any QEMU binary to be executed with: $QEMU_BINARY -M none -qmp stdio Without errors from missing options that are required by various boards. This also provides a mode that we can use in the future to construct machines entirely through QMP commands.
