PCI: add OBFF enable/disable support OBFF (optimized buffer flush/fill), where supported, can help improve energy efficiency by giving devices information about when interrupts and other activity will have a reduced power impact. It requires support from both the device and system (i.e. not only does the device need to respond to OBFF messages, but the platform must be capable of generating and routing them to the end point).
