static_allocator/gpa: deduplicate secondary PCI window list

Browse Source 
When one single device being connected after multiple-levels of PCI-to-PCI
bridges, all those bridges may have the same MMIO window. That causes the
current static allocator not to consider that window being occupied because
of how it detects nested MMIO regions.

Remove duplicates in the list of secondary bus MMIO windows to fix that
issue.
