s390/pci: resize iomap

Browse source

On s390 we need to maintain a mapping between iomem addresses
and arch specific function identifiers. Currently the mapping
table is created as such that we could span the whole iomem
address space. Since we can only map each bar space from each
possible function we have an upper bound for the number of
mapping entries.

This reduces the size of the iomap from 256K to less than 4K
(using the defconfig).
