     - We introduce the `GPIO` driver, which pinmuxes the RPi's PL011 UART.
     - Most importantly, the `PL011Uart` driver: It implements the `console::interface::*` traits and
       is from now on used as the main system console output.

 - We also modify the `panic!` handler, so that it does not anymore rely on `println!`, which uses
   the globally-shared instance of the `UART` that might be locked when an error is encountered (for
