x86-64: allow mapping mmcfg space for high numbered PCI segments

Rather than using the segment number directly when determining the
virtual address for a particular mmconfig block, use the array index
instead. Thus a system with (perhaps significantly) less than 2048 PCI
segments, but with some having numbers beyond 2047 can actually have
all its mmconfig blocks mapped.
