ASoC: dt-bindings: simple-card: correct DAI subnodes pattern

Browse source 
The simple-audio-card,dai-link node does not allow address/size-cells
thus children (cpu, codec) should come without unit addresses.  For
cases with multiple nodes of same type, require a dash before index
(e.g. cpu-x) and add trailing $ to the pattern to disallow other
characters.
