Make the pattern matching node names a bit stricter to improve DTS
consistency.  The pattern is restricted to -N suffixes to decimal
numbers.

Some time ago I did such change treewide, but mux was left out:

Maybe I'm confused, but how is that compatible with the hex I2C
address in Documentation/devicetree/bindings/mux/adi,adg792a.txt?

	&i2c0 {
		mux: mux-controller@50 {
			compatible = "adi,adg792a";

Cheers,
Peter

I'm was indeed confused. The @-tail is .* and the decimal digits have
nothing to do with the address. Sorry for the noise...
