This reverts commit c761028ef5e27f477fe14d2b134164c584fc21ee. The previous device tree correctly reflects the hardware behavior. The reverted commit introduced a fake address translation at pcie's parent bus node. Reverting this change prepares for the cleanup of the driver's cpu_addr_fixup() hook.
