45eb038029 dt-bindings: serial: stm32: Use 'type: object' instead of false for 'additionalProperties' 
[ Upstream commit 9f299d3264 ]

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]+'

Fixes: af1c2d8169 ("dt-bindings: serial: Convert STM32 UART to json-schema")

b2cc2b5111 dt-bindings: serial: add generic DT binding for announcing RTS/CTS lines 
Add support of generic DT binding for annoucing RTS/CTS lines. The initial
binding 'st,hw-flow-control' is not needed anymore since generic binding
is available, but is kept for backward compatibility.

888ae87104 dt-bindings: serial: Document CTS/RTS gpios in STM32 UART 
Document the use of CTS/RTS gpios for flow control in STM32 UART
controller. These properties can be used instead of 'st,hw-flow-ctrl'
for making use of any gpio pins for flow control instead of dedicated
pins. It should be noted that both CTS/RTS and 'st,hw-flow-ctrl'
properties cannot co-exist in a design.
