Subject: [PATCH 1/2] dt-bindings: serial: fix regex pattern for matching serial node children

The regular expression pattern for matching serial node children should
accept only nodes starting and ending with the set of words: bluetooth,
gnss, gps or mcu.  Add missing brackets to enforce such matching.

Fixes: 0c559bc8abfb ("dt-bindings: serial: restrict possible child node names")
Reported-by: Andreas Kemnade <andreas@...nade.info>
Closes: https://lore.kernel.org/all/20231004170021.36b32465@aktux/
