[PATCH] fix ancient breakage in ebus_init()

Back when pci_dev had base_address[], loop of form
	base = &...->base_address[0];
	for (.....) {
		...
		*base++ = addr;
	}
was fine, but when that array got spread in ->resource[...].start
replacing the initialization with
	base = &...->resource[0].start;
was not a sufficient modification.  IOW this code got broken for cases
when there had been more than one resource to fill.  All way back in
2.3.41-pre3...
