This is a set of fixes related to my recent "remove device resource fixups"
series. Patches [1-4] are essential; they fix bugs that prevent machines from
booting. Patches [5-9] don't fix any current issues, so they could be
deferred.
[1] ("fix bridge I/O window bus-to-resource conversion") fixes a mistake
so bus-to-resource conversion of I/O port addresses will work correctly.
[2-4] ("compute I/O space bus-to-resource" and "convert devtree bus
addresses" for powerpc and sparc) fix an oversight: I forgot to apply
bus-to-resource when reading bus addresses from the OF device tree, so
machines using the device tree don't boot.
[5-6] ("don't export pci_flags" and "move <asm-generic/pci-bridge.h>
include") are simple no-op cleanups.
[7-9] are basically a reimplementation of the "EN1K" (1K granularity
for P2P I/O windows) functionality, and removal of the sparc bridge
window reading code, since it is now functionally equivalent to the
generic code.
