Switch to the new console APIs enabled by setting MULTI_CONSOLE_API=1. The crash console doesn't use this API, it uses internally the core functions of the 16550 console. `bl31_plat_runtime_setup` is no longer needed. When this platform port was introduced, that function used to disable the console. It was needed to override that behaviour. The new behaviour is to switch to the runtime console. The console is registered for all scopes (boot, crash and runtime) in `rpi3_console_init` so it is not needed to override the default behaviour anymore. Update documentation.
