Some boards seems to ignore builtin perst configuration and use gpio
instead. This approach seems to be more common. Hence, update the driver
to properly use gpio perst via gpio descriptor's API.
For more information refer to .
Even with this set of patches applied, there still seems to have some issues
with a non stable pci link through the boot process. This will be resolved
in nest patch series when the problem is find.
Patches are only compile-tested. It would be good to test them before being
