Since the pci_dev is no longer held in the provate data, we can
also cleanup the detach a bit. Remove the IS_ENABLED() tests in
the detach. If the pci_dev is non NULL it's a PCI device otherwise
it's an ISA device. Using IS_ENABLED() to omit the code paths
makes the code a bit confusing and doesn't save much.
The detach() routine should really check thisboard->bustype for
robustness, as NULL hw_dev doesn't necessarily mean its a PCI device.
The original code should have checked thisboard->bustype too although it
works by accident because dev->iobase is 0.
