rpi3: console: Use same "clock-less" setup scheme as RPi4
In the wake of the upcoming unification of the console setup code between RPi3 and RPi4, extend the "clock-less" setup scheme to the RPi3. This avoid programming any clocks or baud rate registers, which makes the port more robust against GPU firmware changes.
