arm: turn pr_info() into pr_debug() messages

For whatever reason on ARM/arm64 machines kvmtool greets us with quite
some elaborate messages:
  Info: Loaded kernel to 0x80080000 (18704896 bytes)
  Info: Placing fdt at 0x8fe00000 - 0x8fffffff
  Info: virtio-mmio.devices=0x200@0x10000:36

  Info: virtio-mmio.devices=0x200@0x10200:37

  Info: virtio-mmio.devices=0x200@0x10400:38

This is not really useful information for the casual user, so change
those lines to use pr_debug().
This also fixes the long standing line ending issue for the mmio output.
