[PATCH] ppc64: Make eeh_init function again
My patch "Separate pci bits out of struct device_node" (commit
1635317facea3094ddf34082cd86797efb1d9f7e) had the unfortunate
side-effect that it stopped eeh_init() from working correctly.
It needs the pointers set up by find_and_init_phbs(), but it was being
called just before find_and_init_phbs(). That meant that we didn't
enable EEH (pSeries PCI error recovery) on any devices, and that meant
that on POWER5 systems, the hypervisor wouldn't let us enable memory or
I/O space access to any devices, and their drivers got somewhat
confused.
This fixes it by moving the eeh_init call after find_and_init_phbs.
Tested on a POWER5 partition.
