memory: fix I/O port aliases
Commit e58ac72b6a0 ("ioport: change portio_list not to use
memory_region_set_offset()") started using aliases of I/O memory
regions. Since the IORange used for the I/O was contained in the
target region, the alias information (specifically, the offset
into the region) was lost. This broke -vga std.
Fix by allocating an independent object to hold the IORange and
also the new offset.
Note that I/O memory regions were conceptually broken wrt aliases
in a different way: an alias can cause the same region to appear
twice in an address space, but we had just one IORange to service it.
This patch fixes that problem as well, since we can now have multiple
IORange/MemoryRegion associations.
