[PATCH 5.10 184/530] dt-bindings: serial: stm32: Use type: object instead of false for additionalProperties

[Greg Kroah-Hartman]

From: dillon min <dillon.minfei@xxxxxxxxx>

[ Upstream commit 9f299d3264c67a892af87337dbaa0bdd20830c0c ]

To use additional properties 'bluetooth' on serial, need replace false with
'type: object' for 'additionalProperties' to make it as a node, else will
run into dtbs_check warnings.

'arch/arm/boot/dts/stm32h750i-art-pi.dt.yaml: serial@40004800:
'bluetooth' does not match any of the regexes: 'pinctrl-[0-9]+'
