The patch also enables CONFIG_DEVTMPFS_MOUNT, but doesn't mention it, so the following is what I've queued for v5.2-rc.

Let's enable MMC & SPI drivers as well so that one can boot to the user space using default config in upstream kernel. While here, enable automatic mounting of devtmpfs to simplify kernel testing with minimal root filesystems.
