Add support for writing to mapping high memory for pccard memory
windows. Right now we only support pci chips that are memory mapped.
These are the most common bridges in use today and will help a large
majority of the users.
I/O mapped PCI chips support this functionality in a different way, as
do some of the ISA bridges (but only when mounted on a motherboard).
These chips are not supported by this change.
