Revert "platform/x86: p2sb: Allow p2sb_bar() calls during PCI device probe"
commit b20712e853305cbd04673f02b7e52ba5b12c11a9 upstream.
This reverts commit b28ff7a7c3245d7f62acc20f15b4361292fe4117.
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.
