Now we use the IORESOURCE_STARTALIGN to identify bridge resources

set flag IORESOURCE_STARTALIGN for SR-IOV resources in some cases,
for example, using the option "noresize" of parameter
"pci=resource_alignment".

In this patch, we try to use a more robust way to identify
bridge resources.

Yongji, I think this doesn't have to be part of this series, meaning
it can be sent or merged separately.


Seems like I give a wrong example in my changelog. The
parameter "pci=resource_alignment" would not set flag
IORESOURCE_STARTALIGN for SR-IOV resources as I replied
to you in previous patch. So this patch has nothing to do
with this series now, I will remove it as you suggested.

Thanks,
Yongji
