pci: implement pci bridge filtering.
This patch implements pci bridge filtering.
TODO: currently almost all the map funcions assumes
filtered_size == size and addr & ~(size - 1) == addr.
However with bridge filtering, they aren't always true.
Teach them such cases, such that filtered_size < size and
addr & (size - 1) != 0.
