At the moment, this enables memory and io unconditionally.  But I think
it should check BAR is assigned before enabling and using it, since
e.g. pci express devices might not have their BARs assigned.

I'm also not sure 64 bit BAR values will work under ipxe -
if not it's preferably to fall back on io or cfg access.
