I will add gpio-beeper by modifying the device tree.
Because now CM5 starts to use RP1 controller gpio40 （Standard 40-pin GPIO header via RP1 Southbridge）.
I used to have it working fine on cm4.I guess bcm2712-rpi-cm5.dtsi should be modified.But I don't know the corresponding pin number. Should I still write 19?
