Revert "pcdp: use early_ioremap/early_iounmap to access pcdp table"

This reverts commit 2af3af56, which was
commit 6c4088ac upstream.

This broke compilation of the driver in 2.6.32.y as the
early_io{remap,unmap}() functions are not defined for ia64.  The driver
can *only* be built for ia64 (even in current mainline), so a fix for
x86_64 is pointless.
