scripts: dts: Match alpha numeric property values

For using alpha numeric property values in a devicetree node, we
need to match the values starts with a number. Current scenario will
return the value as a numeric literal if it starts with a number. This
will not work for a compatible like, "96b-ls-con" which is proposed in
issue #15598.
