Shin'ichiro Kawasaki 74c4c7d57c Revert "platform/x86: p2sb: Allow p2sb_bar() calls during PCI device probe" 
commit b20712e853 upstream.

This reverts commit b28ff7a7c3.

The commit introduced P2SB device scan and resource cache during the
boot process to avoid deadlock. But it caused detection failure of
IDE controllers on old systems [1]. The IDE controllers on old systems
and P2SB devices on newer systems have same PCI DEVFN. It is suspected
the confusion between those two is the failure cause. Revert the change
at this moment until the proper solution gets ready.
