CI builds fail on a dtb. Can you check it, @leon-anavi ?

I fixed with two changes:

• Set PREFERRED_VERSION_linux-raspberrypi = "6.1%" in the configuration for raspberrypi5
• Left bcm2712-rpi-5-b.dtb in RPI_KERNEL_DEVICETREE only for raspberrypi5 because other machines by use older version of the kernel where the dts is not present.

Best regards, Leon
