PS4, Line 9: Devices of class type "system" are arbitrary devices and it's not clear
           : which of them need bus mastering. Therefore, enable bus mastering
           : conditionally based on Kconfig option PCI_ALLOW_BUS_MASTER_ANY_DEVICE.
           : 
hmm. as a user, what when I want to enable *any* devices but not system-class devices? I'd have to select "any devices" even if didn't want this. I'd add another Kconfig with `default y`
