rpi3: Use new console APIs
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.
