PCI PM: Do not disable and enable bridges during suspend-resume

Browse source

It is a mistake to disable and enable PCI bridges and PCI Express
ports during suspend-resume, at least at the time when it is
currently done.  Disabling them may lead to problems with accessing
devices behind them and they should be automatically enabled when
their standard config spaces are restored.  Fix this by not attempting
to disable bridges during suspend and enable them during resume.
