Instead of consulting vbt.ports[] lets just go through the
whole child device list to check whether a specific port
was declared by the VBT or not.
Note that this doesn't change anything wrt. detecting duplicate
child devices with the same port as vbt.ports[] would also always
contain exactly one of the duplicates.
v2: Include a is_port_valid() check to deal with some broken VBTs
Mention something about duplicate port detection (Jani)
