rpi4: Add stdout-path to device tree
Some device tree users like to find a pointer to the standard serial console in the device tree, in the "stdout-path" property of the /chosen node. Add the location of the Mini UART in that property, so that DT users are happy, for instance Linux' earlycon detection.
