dt-bindings: serial: fix regex pattern for matching serial node children

Browse Source 
[ Upstream commit 42851dfd4dbe38e34724a00063a9fad5cfc48dcd ]

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.
