[PATCH v2 1/3] dt-bindings: net: pse-pd: Update regex pattern for ethernet-pse nodes

[Oleksij Rempel]

This patch modifies the regex pattern for the $nodename property in the
device tree bindings documentation for PSE-PD controllers. The updated
pattern allows for additional node names, including those with a hyphen
followed by a hexadecimal digit.

Before this change, the pattern ^ethernet-pse(@.*)?$ only allowed for
node names like "ethernet-pse" or "ethernet-pse at 1". With the new pattern
node names like "ethernet-pse-1" are now also valid.
