Revert "PCI: fix IDE legacy mode resources"
This reverts commit fd6e732186ab522c812ab19c2c5e5befb8ec8115, which
helped up things on MIPS, but was wrong for everything else. As Ralf
Baechle puts it:
"It seems the whole MIPS resource managment is complicated enough (out
of necessity) that only a few people actually grok it. Ioports being
actually memory mapped on MIPS only makes the confusion worse, sigh."
