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.
