[PATCH 19/20] hw/arm/sbsa-ref: Tidy up use of RAMLIMIT_GB definition

[Philippe Mathieu-Daudé]

Define RAMLIMIT_BYTES using the TiB definition and display
the error parsed with size_to_str():

  $ qemu-system-aarch64-unsigned -M sbsa-ref -m 9T
  qemu-system-aarch64-unsigned: sbsa-ref: cannot model more than 8 TiB of RAM
