Reset PCI driver?

[Bryce Edwards]

I was experimenting with passing thru one of my PCI devices and ran the
commands:

s devctl detach pci0:20:0
s devctl set driver pci0:20:0 ppt

It seems to have reset many of my PCI items to no longer have a driver.
See my pciconf output below.  To fix it back, I tried "sudo devctl clear
driver -f pci0" and it didn't do anything.  Also, this persists past full
power cycle, which strikes me as odd.  Before I ran the detach, there
weren't any none* pci devices.
