Subject: [PATCH v3 9/9] dt-bindings: serial: stm32: add phandle 'bluetooth' to fix dtbs_check warrning

From: dillon min <dillon.minfei@...il.com>

when run make dtbs_check with 'bluetoothi brcm,bcm43438-bt'
dts enabled on stm32h7, there is a warrning popup:

>> arch/arm/boot/dts/stm32h750i-art-pi.dt.yaml: serial@...04800: 'bluetooth'
   does not match any of the regexes: 'pinctrl-[0-9]+'

to make dtbs_check happy, so add a phandle bluetooth

Fixes: 500cdb23d608 ("ARM: dts: stm32: Add STM32H743 MCU and STM32H743i-EVAL board")
