vl.c: Extend get_boot_devices_list() to ignore suffixes

As suffixes do not make sense for sPAPR's device tree and
there is no way to filter them out on the BusState::get_fw_dev_path()
level, let's add an ability for the external caller to specify
whether to apply suffixes or not.

We could handle suffixes in SLOF (ignored for now) but this would require
serious rework in the node opening code in SLOF, which has no obvious
benefit for the currently emulated sPAPR machine.
