This means VPD LID is already loaded before we start preloading
kernel and initramfs LIDs, thus ensuring VPD doesn't have to wait
for them to finish being read from FSP.

The opal eeh interrupt handlers raise an opal event
(OPAL_EVENT_PCI_ERROR) whenever there is some processing required from
the OS. The OS then needs to call opal_pci_next_error(...) in a loop
passing each phb in turn to clear the event.
However opal_pci_next_error(...) clears the event unconditionally
meaning it would be possible for eeh events to be cleared without
processing them leading to missed events.
This patch fixes the problem by keeping track of eeh events on a
per-phb basis and only clearing the opal event once all phb eeh events
have been cleared.

Now that opal.h includes opal-api.h, there are a bunch of files that
include both but don't need to.

This is probably not the best collection of things in the world,
but it means that opal.h is much closer to being directly usable
by an OS.
This triggers a bunch of #include fixes throughout the tree.
