hw/arm/integratorcp: Map the audio codec controller

The Linux kernel displays errors why trying to detect the PL041
audio interface:

  Linux version 4.16.0 (linus@genomnajs) (gcc version 7.2.1 20171011 (Linaro GCC 7.2-2017.11)) #142 PREEMPT Wed May 9 13:24:55 CEST 2018
  CPU: ARM926EJ-S [41069265] revision 5 (ARMv5TEJ), cr=00093177
  CPU: VIVT data cache, VIVT instruction cache
  OF: fdt: Machine model: ARM Integrator/CP
  ...
  OF: amba_device_add() failed (-19) for /fpga/aaci@1d000000

Since we have it already modelled, simply plug it.
