fbdev/core: Remove remove_conflicting_pci_framebuffers()
Remove remove_conflicting_pci_framebuffers() and implement similar functionality in aperture_remove_conflicting_pci_device(), which was the only caller. Removes an otherwise unused interface and streamlines the aperture helper. No functional changes.
