dt-bindings: arm: coresight: Update the pattern of ete node name

The device full name is embedded trace extension. There is no good fit
in generic names list for the embedded trace extension. ETE is abbreviation
of embedded trace extension and the number is the CPU number that ete is
associated. Change the pattern of the node name as it won't affect any
device tree node as of now.
