[PATCH v2 06/71] bootstd: Simplify locating existing bootdevs

There is no point in trying to match the alias order for bootdevs, since
build_order() either sorts them by priority, uses the boot_targets
environment variable or the bootdev-order property.

Just use the iterator instead, to simplify the code.
