The bcm2712 found on the Raspberry Pi 5 is available in the d Stepping
and in a c Stepping. There are two separate dts files. The
bcm2712-rpi-5-b.dts for the c Stepping and the bcm2712-d-rpi-5-b.dts for
the d Stepping. The d stepping does not set its own compatible/model
string but uses "raspberrypi,5-model-b".
These two steppings are not compatible. Booting with the wrong dtb file
causes a crash at boot.
Add a compatibles string "raspberrypi,5-model-b-d0" to allow us to
distinguish between those two steppings.
