[PATCH master] boards: qemu-virt: rescan aliases after merging DT fragment

[Ahmad Fatoum]

barebox now compiles an initially empty device tree that's combined with
the device tree passed by Qemu. That device tree can hold the FIT public
key or if CONFIG_EXTERNAL_DTS_FRAGMENTS is enabled, device tree nodes
passed at build time. If this device tree fragment adds an alias, it
won't be registered, which can be surprising. Therefore call
of_alias_scan after merging the device trees.
