[PATCH] ppc64: Make eeh_init function again

[Paul Mackerras]

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, since
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.
