ide/powermac: Fix use of uninitialized pointer on media-bay
The current ide-pmac calls media_bay_set_ide_infos() with an
uninitialized "hwif" argument. The proper fix is to split the
allocation of the hwif from its registration in order to properly
setup the mediabay informations before registration.
