powerpc/eeh: sysfs entries lost
The sysfs entries are lost because of commit 2213fb1 ("powerpc/eeh:
Skip eeh sysfs when eeh is disabled"). That commit added condition
to create sysfs entries with EEH_ENABLED, which isn't populated
when trying to create sysfs entries on PowerNV platform during system
boot time. The patch fixes the issue by:
* Reoder EEH initialization functions so that they're same on
PowerNV/pSeries.
* Cache PE's primary bus by PowerNV platform instead of EEH core
to avoid kernel crash caused by the function reorder. Another
benefit with this is to avoid one eeh_probe_mode_dev() in EEH
core.
