Fix the following crash, seen in dwc/pci-imx6.

Hardware name: Freescale i.MX6 Quad/DualLite (Device Tree)
task: cb850000 task.stack: cb84e000
PC is at imx6_pcie_probe+0x2f4/0x414
...
While at it, fix the same problem in various drivers instead of waiting for
individual crash reports.
The change in the imx6 driver was tested with qemu. The changes in other
drivers are based on code inspection and have been compile tested only.
