Fix the detection of PCI serial ports with sysfs and without udevv5.2.0-rc1
Unfortunately, 0973537c5471288726b929250199a41435729bee caused a serious
regression for obtaining detecting PCI serial ports without udev. This was
working before since the hard coded fallback mechanism has been up to this task,
but the sysfs alternative took the precedence over.
A note has also been added to the udev part of the algorithm because we will
need to obtain the vendor and product identifiers in a separate block in the
future. The vid/pid will be fixed in a separate change once that is well-tested.
This patch has no any risk as far as I can tell since it is just adding a new
short block to the existing code without much implication.
I have tested the change on Linux for my use cases with Qt 4 and then 5, and I
cannot find any regression. Everything works as expected both with udev and
without, i.e. with sysfs.
Thanks go to Aaron Linville for reporting the issue.
