[PATCH v5 9/9] dt-bindings: serial: stm32: Use 'type: object' instead of false for 'additionalProperties'

[dillon.minfei at gmail.com]

From: dillon min <dillon.minfei at gmail.com>

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 at 40004800:
'bluetooth' does not match any of the regexes: 'pinctrl-[0-9]+'

Fixes: af1c2d81695b ("dt-bindings: serial: Convert STM32 UART to json-schema")

v5: accroding to rob's suggestion, replace false with 'type: object'
    of 'additionalProperties'.
