* Change the virt board's default interface type for block devices to virtio
  * Improve some error messages that will now be triggered by some incorrect
    but previously worked-by-accident command lines
  * Print ELR if we're doing debug logging of AArch64 exception entry
  * Handle the "completely empty semihosting commandline" correctly for
    softmmu (we already did for linux-user)
  * Add GICv2m description to ACPI tables for virt board
  * Fix some incorrect table revision entries in virt board ACPI tables
