From: dillon min <dillon.minfei@xxxxxxxxx>
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@40004800: '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")
