This moves BCR defines to the common header and immediately makes use of
them to add BCR_APROMWE, replacing the open-coded write check in

The core pcnet emulation code is used by both the PCI "pcnet" device
and the SPARC "lance" device.  Split the common code frm the PCI code so
that that can be configures independantly.
