hmm, the vendor devicetree uses active high but does not set
reset-gpio-active-high. In a quick test it turned out that setting this
property keeps the pci bus in reset.
In fact, the linux driver ignores the polarity and falls back to active
low. This explains why specifying active high "worked" here...

So you are right and it should be active low. I'll fix that.
