We're going to reserve/assign PEs when pcibios_setup_bridge() is
called. The function won't be called for root bus as it doesn't
have parent bridge. However, the root bus still needs a PE to be
covered.

This reserves PE numbers that are adjacent to the reserved one
for root buses.


Somewhere in the patchset you need to describe why you need a separate PE for
a root bus and why reserved_pe_idx is not enough for this.


Please confirm if it's fine to add the descrption in this patch's chagelog.

Yes, it is fine. Thanks!
