This will probe the multiplexer devices that have a "u-boot,mux-autoprobe"

Is "u-boot,mux-autoprobe" a required property? The fact that its in DT
makes me think its optional. If that's the case, above printf() should
be reduced to debug() to avoid confusion
Thanks Vignesh. It was for debug and forgot to remove it.
