bcm2835_aux: add emulation of BCM2835 AUX (aka UART1) block

Browse source 
At present only the core UART functions (data path for tx/rx) are
implemented, which is enough for UEFI to boot. The following
features/registers are unimplemented:
  * Line/modem control
  * Scratch register
  * Extra control
  * Baudrate
  * SPI interfaces
