From Boris Brezillon:

"""
Fixes for 4.10-rc3
- Forbid compiling xway NAND controller driver as a module
- Fix tango NAND DT binding and make sure the controller is in a clean
  state at probe time
- Add dependency on HAS_IOMEM to the oxnas NAND driver
- Fix irq number validity check in the lpc32xx driver
