At the moment the UART input clock rate is hard coded at compile time. This works as long as the GPU firmware always sets up the same rate, which does not seem to be true for the Raspberry Pi 4. In preparation for being able to change this at runtime, add a base clock parameter to the console setup function. This is still hardcoded for the Raspberry Pi 3.
