Actually I like these prints when developing/fixing stuff, it's a clear
indication of what's been discovered that is available even if for some
reason my rootfs is not available (which is common when the rootfs is
on a spi-nor).

So I would not trash all these lines personally... I believe the
dev_info can be lowered if you prefer, but dev_dbg is already meant for
debugging purposes and will anyway be discarded by default.
