Actually I misspoke; we should modify pci_enable_io_method() so that we
can indicate a failure to enable the requested space.
This would keep drivers from having to check and see if PCIM_CMD_PORTEN or
PCIM_CMD_MEMEN is set.
This requires changing the definition of the 'enable_io' method.
Since we're here we should change 'disable_io' and
'{enable,disable}_busmaster' as well.
